Lutron GCH-2018 CO2 Meter with Humidity, Temperature and Dew Point

The Lutron GCH-2018 is a two-probe instrument that measures carbon dioxide (CO2) and temperature on one probe and relative humidity, dew point and temperature on the other. CO2 is measured by the NDIR method for stable long-term operation, and the separate probes make remote and duct measurements easy. The meter includes a CO2 alarm setting, altitude compensation, min/max memory recall and an RS-232/USB computer interface, and ships in a hard carrying case.

NDIR measuring principle for CO2 (carbon dioxide), suitable for long-term operation.
High repeatability and high accuracy.
Two probes: one for CO2 and temperature, the other for humidity, temperature and dew point.
Separate probes for easy operation and convenient remote measurement.
CO2 function with alarm setting.
Humidity measurement with fast response time.
Large S-TN LCD with high contrast for easy readout.
Data hold function freezes the desired value on the display.
Records maximum and minimum readings with recall.
RS-232/USB computer interface.
Microprocessor circuit assures maximum possible accuracy and provides special functions and features.
Heavy duty, compact housing with hard carrying case, designed for easy transport and operation.
Auto shut off saves battery life.
Powered by batteries or a DC 9V adapter.

Electrical Specifications

Specifications apply at 23 ± 5 °C.

CO2 (Carbon Dioxide)

Range	0 to 4,000 ppm
Resolution	1 ppm
Accuracy	± 40 ppm at 1,000 ppm and below.
	± 5% of reading above 1,000 ppm through 3,000 ppm.
	± 250 ppm typical above 3,000 ppm (reference only).
Repeatability	± 20 ppm at 3,000 ppm and below.

Temperature (CO2 Probe)

Range	0 to 50 °C, 32 to 122 °F
Resolution	0.1 degree
Accuracy	± 0.8 °C, ± 1.5 °F

Humidity

Range	10% to 95% RH
Resolution	0.1% RH
Accuracy	± (3% of reading + 1% RH) at 70% RH and above.
Accuracy	± 3% RH below 70% RH.

Temperature (Humidity Probe)

Range	0 to 50 °C, 32 to 122 °F
Resolution	0.1 degree
Accuracy	± 0.8 °C, ± 1.5 °F

Dew Point

°C	Range	-25.3 to 48.9 °C
°C	Resolution	0.1 °C
