Question: Does this device have an emergency alarm, so that it will wake you up if there CO gas is in the room? Suitable for travel?
Document: A bit expensive, but so are the competitors.I found this to be a device worth researching before buying. I am a landlord so I use these in all of my buildings at one time or another and in my home so accuracy and quality are high on my priority list.Alarm sounds at 200PPM+Battery life seems strong thus far, plus it is includedClaims to have a 3 year life on the sensorFast samplings and the device itself seems well made.
Exactly what i was looking for to determine co levels, Easy to use. I found out the gas lights in my camp were producing co but not at dangerous levels.
It works, but I don't know anything about its accuracy. It often settles at a reading of 2 PPM.The red rubber is just an obstruction. I couldn't cleanly take it off, so I cut it off and discarded it. (-1 star for this junk. )Opening the battery compartment in the back of the device requires a small phillips screwdriver. There is a packaged 9V battery inside which can be unpacked and connected to its socket.
Features i like: it has an alarm the rings over 200 ppm so if you are in a space with dangerous levels-this thing is gonna go off and tell you to get out fast. They claim three year sensor life- that remains to be seen- but at the rate i use it-this should last a long time(it auto-shuts off which should help with battery replacement hassles. The lcd is clear and the controls rock bottom simple to use.
I have used it several times and it appears accurate. It is a good tool to have to verify the problem when the CO detector goes off.
Works very well. Use it in my home to make sure no CO leaks, as I use woodburning stove. I have CO alarms buT I like being able to check around the wood stove to make sure.
I have been, so far, very pleased with this CO tester the red protective cover isn't impossible to put on like I've read on other reviews. It seems very durable. Even the black case it comes with is padded for extra protection. I recommend this product!
We had two Carbon Monoxide alarms go off last week in our home and I bought this to take spot readings. Solidly built and easy to operate with protective red casing and a pocket pouch. Display is easy to read and audible alert to CO level is good. I am very pleased with the price and quality of this product.
Good product for the price... I tested this side-by-side with a Draeger CO detector, and it read CO concentrations as well as the more expensive meter, possibly with a bit quicker response. So far, no complaints. It has a slight 'quirk' of not dropping back to zero in clear air (stays at 1-2), but doesn't affect the operation. Would recommend, and would purchase it again.
I cannot vouch for the precision, but the unit works fine and does detect CO as expected. The battery is sealed in plastic packaging when you receive the unit, so you will need to slip the red rubber off the enclosure and connect the 9v battery.This unit looks like it is a Pyle branded version of the standard GSI HT-1000. You actually pay $8 for the "cool" red rubber.
Answer: yes
