PCD100 Carbon Monoxide Detector, Handheld CO Meter with Temperature | Humidity Sensor, Type-C Rechargeable 100H Battery, 0-1000 PPM +/-5 PPM Accuracy, Custom High/Low Alarms, MAX/AVG & Hold

Carbon monoxide is colorless, odorless, and tasteless - the only way to know it's there is to measure it. The SENSYX PCD100 Rechargeable Carbon Monoxide Meter with Temperature & Humidity puts reliable CO monitoring in your pocket. Its electrochemical sensor measures CO concentration from 0 to 1000 PPM with 1 PPM resolution and +/-5 PPM accuracy, while dual precision sensors simultaneously track ambient temperature (-22 to 158 F, switchable to Celsius) and humidity (0 to 100% RH) - all displayed together on a large VA LCD with two-color backlight. Alarms work the way you need them to. Set your own high and low alarm thresholds; when CO levels cross a limit, the display flashes red and the buzzer sounds - slow beeps for the low alarm, rapid beeps for the high alarm. Need silence? One press of the mute button turns off the buzzer while visual monitoring continues. Professional functions make inspections easier: the PCD100 records the peak CO level detected, calculates the average concentration over your measurement session, and the hold function freezes the current reading so you can note it down accurately. Powered by a built-in 1500mAh rechargeable lithium-ion battery with Type-C charging, it runs up to 100 hours per charge with up to 120 hours of standby. At just 3.88 oz and 5.59 inches tall, it goes wherever you work - homes, garages, boiler rooms, campsites, RVs, and job sites. 10-year sensor work life, backed by a 2-year limited warranty.

• ACCURATE CO MEASUREMENT: Built-in electrochemical sensor detects carbon monoxide from 0 to 1000 PPM with 1 PPM resolution and accuracy of +/-5 PPM; the 10-year sensor work life delivers dependable long-term monitoring you can count on
• TEMPERATURE & HUMIDITY MONITORING: Dual precision sensors also measure ambient temperature from -22 to 158 Fahrenheit (F/C switchable) and humidity from 0 to 100% RH, displayed together with real-time CO levels on a large VA LCD with two-color backlight
• CUSTOMIZABLE HIGH & LOW ALARMS: Set your own high and low alarm thresholds to match your safety standards; when CO exceeds a limit, the display flashes red while the buzzer beeps slowly (low alarm) or rapidly (high alarm), with one-touch mute for silent monitoring
• MAX, AVG & DATA HOLD: Records the peak CO concentration detected since power-on, calculates the average level over your measurement session, and the hold function freezes the current reading for easy note-taking - ideal for inspections and safety reports
• RECHARGEABLE & POCKET-SIZED: 1500mAh lithium-ion battery delivers up to 100 hours of operation and 120 hours of standby per Type-C charge; lightweight 3.88 oz body goes anywhere from boiler rooms to campsites, backed by a 2-year limited warranty
