<p>[Powerful function] This portable CO gas monitoring tester can continuously monitor the CO concentration in the surrounding environment. Make sure to detect excessive CO gas and remind the operator to take relevant measures.</p> <p>[Precision and durability] The high-precision detector has an automatic calibration function. The measurable CO concentration range is 0~1000PPM (accuracy is 1PPM). It can use two temperature units (\u2103 and \u2109) (temperature range: 32~122\u2109\/0~50\u2103). The shell of the CO detector is made of high-quality ABS engineering plastic, which is comfortable to the contact, strong and durable. The service life of the sensor of this product is as long as 3 years.</p> <p>[Practical design] The CO gas tester is small in size (5.39 X 1.97 X 1.04 cm), light in weight (0.25 pounds (about 0.1 kg), easy to carry and operate. Even in the dark and other harsh environments, you can easily use the high-definition LCD backlight Screen. In addition, you can set whether to turn on automatic shutdown (when the automatic shutdown function is turned on, if there is no operation for 10 minutes, it will automatically turn off to save power).</p> <p>[Application range] The carbon monoxide tester has the characteristics of wide measurement range, high measurement accuracy, small size, convenient carrying and operation. It is widely used in coal, petroleum, textile, chemistry, metallurgy, paper making, fire protection, municipal administration and other industries.</p> <p>Colour: as shown</p> <p>Material: plastic</p> <p>Package Contents:</p> <p>1 * Carbon Monoxide Meter</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
