Extech CO260 – Meter/Datalogger for Carbon Monoxide, Carbon Dioxide and IAQ

• Measures CO, CO2, air temperature and RH
• Displays dew point and wet bulb based on calculations
• Programmable CO warning level with audible alarm
• Calculates statistical weighted averages for CO2
• Continuous datalogging up to 32K readings

The CO260 measures CO2 (Carbon Dioxide) levels, CO (Carbon Monoxide) levels, air temperature, and relative humidity. The CO260 also displays dew point and wet bulb temperatures, generated from calculations performed on temperature and humidity measurements. The CO260 is an ideal instrument for indoor air quality (IAQ) analysis. This device is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

The CO260 can also datalog manually up to 99 readings with internal memory or continuously up to 32K readings with included software.

Taking measurements

The meter begins measuring in the selected mode, when powered on, and the sensor responds every 1 second. If the operating environment changes (example: from high to low temperature), it requires 30 seconds for the CO2 sensor to respond and up to 30 minutes for the relative humidity sensor to respond.

MIN, MAX, STEL, TWA Recording

In MIN and MAX modes, the meter shows the lowest (minimum) or highest (maximum) reading in the primary display.

In STEL (short term exposure limit) and TWA (time weighted average) modes, the main display shows the weighted average of readings for the past 15 minutes (STEL) or 8 hours (TWA). TWA and STEL mode are only operational in CO2 mode.

In CURRENT mode, the primary display shows the current readings. The secondary display shows the elapsed timer.

Automatic Datalogging

The CO260 automatically records CO2, CO, Temperature, or RH readings and can store up to 32,000 records. The sample rate can be set from 1 second to 4 hours 59 minutes and 59 seconds. Previous records are overwritten any time logging is started.

CO Alarm

The meter features an audible alarm (80db beep) that warns when CO concentration exceeds the set limit. The beeper stops when the readings fall below the limit. The meter beeps again if the value exceeds the limit.

PC Interface

This meter has the capability to connect to and communicate with a PC. To install and use the software, please refer to the instructions provided on the supplied CD-ROM and/or the instructions provided in the HELP Utility within the software program.
