Carbon Monoxide Meter
Carbon monoxide (CO) is a toxic gas. OSHA emphasizes that carbon monoxide is a poisonous, colorless, odorless, and tasteless gas – making it very elusive. Although CO has no smell, it is often mixed with other gases that do have an odor (i.e. exhaust gas). When carbon monoxide is inhaled, your body replaces the oxygen in your red blood cells with carbon monoxide.
USA NIST Traceable Source Calibration
Have the highest confidence in your gas detection accuracy. Possible only with best calibration practices to USA NIST Traceable Sources. Calibration qualified in the Forensics Detectors laboratory, located in Los Angeles, California, USA.

Simply does what it is supposed to do, report CO levels quickly and reliably.
This is the second Forensics CO meter we have purchased. The first one is used in our Sprinter van as the primary CO sensor in case something goes wrong with the diesel “parking” heater. It responds much more quickly to CO level changes compared to standard consumer-grade household detectors, and instills far more confidence in its detection and alarm capabilities than the latter. For that reason we have purchased this second unit for our house, and plan to use it for continuous monitoring just in case something goes amiss with the gas furnace (there still are 4 household CO sensors in place as backups). Definitely satisfied with this CO detector, and plan to get a third one next year as a gift for our daughter’s house.

CO detector
Fast, works great

Requires expensive calibration to be of value
This unit must be calibrated to be of value. To calibrate you can: 1) send it to the vendor – cost $75 plus one-way shipping, 2) Buy calibration gas – $140 plus $99 for a gas regulator (pressure/flow valve) for a total of $239.I suppose all such units should be calibrated, but paying $239 to calibrate a $89 item seems excessive.I guess you will have to determine if your life is worth $239.In any case, the calibration requirement should have been highlighted in the display write up.The unit does appear to be well built.

nice product
this is a quality product that performs well. suitable for professionals on the go. I want to get their other monitor which may be more suitable for daily home or travel.

What I would have liked to know before purchasing
I wish the description would have included: a. this needs to be recalibrated every 6 months with testing equipment I don’t have, b. it will last only 2-3 years, and c. it is not intended for constant use. I did not discover these points until I opened the box and read the instructions.

Great meter
Bought to measure CO emissions from my vent-free, propane-fired gas log set. After measuring zero, I called the mfgr to get testing method for the meter and yup, it works fine. Log set is burning clean. Will use it to test other propane heaters in my garage and hoop-house.

Too difficult to understand
Plus the print on the directions is so small, one needs a magnifying glass to read them…and they are so difficult and unclear that, for me, product was a waste of my money and time

Works Well
I was worried about the venting of our gas water heater and the usual CO alarms don’t actually read at low levels. This unit was reading “0” so I wasn’t sure it was working. We own 11 old cars ranging from 1956 to 1968. Out the garage, after starting a car and having the meter near the exhaust, it started reading in single then double digits and then alarmed at the low level I set. Moving away from the car, the level settled down to 20 ppm or so. So I trust the device. Not too hung up about calibration in the future. Just want to know if the levels go up without an alarm. This is meant to wear for personal protection so in that case it would be calibrated. I might get the pump to make the readings more instantaneous. Otherwise, unless the air you want to sample is blowing, you have to wait until the environment finds its way into the sensor. Instructions might be confusing for some but they’re fine IMHO.

E’ possibile e facile fissare il livello di allarme per la presenza di monossido di carbonio CO al livello desiderato, e fatte tutte le verifiche del caso, l’allarme funziona molto bene. Batteria ricaricabile, che dura alcuni giorni e si ricarica in poche ore. Sono molto soddisfatto del’acquisto, anche se l’oggetto e’ un po’ caro. Arrivato puntualissimo dagli USA, senza alcuna spesa addizionale

Ein sehr guter und zuverlässiger CO warner.Benutze ihn seit Jahren bei der Arbeit, die Messergebnisse sind immer 100% richtig.Kann ich nur empfehlen 👍

Wirklich leicht zu bedienen, Akku hällt wirklich eine Ewigkeit, Alarm ist trotz BoseA20 deutlich hörbar und die Schwellensicht auch individuell einzurichten wenn dies wer benötigt.Echt den Preis wert

Einer der wenigen CO-Melder die man- bei regelmäßigem Umgang mit offener Verbrennung -kaufen sollte.Warum?Vorteile:+ Kalibrierzertifikat dabei (wichtiger als du glaubst, das ist Nr.1. Ein unzuverlässiger Melder ist noch gefährlicher als kein Melder)+ Warnt sofort+ Misst schon ab 2ppm Konzentration. Andere zeigen mal vielleicht bei 20 etwas an.+ Zwei Alarm-Grenzwerte frei einstellbar+ Piept nicht nur, sondern leuchtet und vibriert zusätzlich+ Misst in Echtzeit und der Messert klingt an frischer Luft auch sofort wieder ab+ Hat Funktion zum regelmäßig selber kalibrieren+ Display bleibt nach Unterschreiten des Grenzwertes noch 30sec beleuchtet.+ Wasserdicht usw. (habe ich nicht getestet)Kritikpunkte:- Leider piept, blinkt und vibriert der Melder bei Erreichen des zweiten Grenzwertes einfach nur schneller.Ich hätte mir beim zweiten Grenzwert dann einen richtig lauten Alarm gewünscht.- Verwendet mini-USB, echt Steinzeit. Also heißts: das extra Kabel immer dabei haben- Akkulaufzeit (immer eingeschaltet) nur 3-4 Tage bei Raumtemperatur- Anzeige der Temperatur nur in Fahrenheit, nicht auf °C umstellbar(Trick: 20°f sind 0°C. 10°f sind wie 5°C (sehr grob). Also entsprechen 60°f ca. 20°C- Etwas klobig, könnte flacher seinWichtige Info:So gut wie alle CO-Melder auf Amazon lösen den Alarm z.B. erst nach mehreren Stunden bei 50ppm aus, dieser hier warnt sofort bei eingestelltem Grenzwert.————-Mit einem anderen CO-Melder von Amazon habe ich schon eine leichte Kohlenmonoxid-Vergiftung bekommen!————-Als der Ei208D Melder endlich ausgelöst hat war es schon passiert.Fühlt sich ca. so an wie 48h durchgemacht/nicht geschlafen. Keine Atemnot aber man fühlt sich erledigt. War nach 24h wieder abgeklungen aber es war echt unnötig und wäre absolut vermeidbar gewesen!Dieser Melder ist zwar im Vergleich zu anderen Meldern nicht ohrenbetäubend laut, aber ich brauche alle meine Nachbarn auch wirklich nicht 2x pro Abend wissen lassen, wann es bei mir Zeit ist zu lüften :)Ich habe ihn derzeit auf 5ppm eingestellt, selbst das ist fast schon körperlich spürbar, bis sich die Konzentration im Raum aufgebaut hat. Fast zu viel. Ich denke ich werde runter auf 3ppm gehen.Fazit:Bei regelmäßigem Umgang mit Verbrennungs-Heizungen absolut seine 130€ Wert um seine Gesundheit zu schonen. (Regelmäßige leichte CO-Vergiftungen können Langzeitfolgen haben).Ich würde ihm anhand seiner Überlegenheit zu fast anderen Meldern auf Amazon eigentlich 5 Sterne geben.4 Sterne nur, weil der Melder einen Tick mehr up-to-date sein könnte (USB-C, °C etc.)Um eine Kohlenmonoxid Vergiftung grundlegend zu überleben reicht aber auch jeder andere (ISO-zertifizierte) CO-Melder für 40€.Noch billiger würde ich keinesfalls einen kaufen.

ich hoffe das es im Notfall auch funktioniert
