Hand-Held Digital Environmental Meter w/ CO2, RH & Temp - General Tools & Instruments

The General Tools & Instruments CDM77535 Hand-Held Digital Environmental Meter provides comprehensive indoor air quality (IAQ) diagnostics for professional use. This robust, portable instrument accurately measures CO2 levels, relative humidity (RH), and air temperature, delivering crucial data for maintaining optimal environmental conditions in a variety of settings.

Key Features

• Utilizes stable Non-dispersive infrared (NDIR) technology for precise CO2 detection within a 0-5000ppm range.
• Offers simultaneous triple displays of CO2 concentration, air temperature, and relative humidity for immediate analysis.
• Measures additional environmental parameters including dew point and wet bulb temperature.
• Calculates Time-Weighted Average (TWA) for 8 hours and Short-Term Exposure Limit (STEL) for 15 minutes, crucial for occupational safety assessments.
• Features an audible CO2 warning alarm and a clear backlight display for visibility in diverse working environments.
• Equipped with an RS232 interface for data logging and analysis, compatible with an optional software kit.

Applications

This environmental meter is an essential tool for professionals tasked with monitoring and managing air quality across various facilities. It is ideally suited for diagnosing IAQ in commercial offices, educational institutions, manufacturing plants, healthcare facilities, and hospitality environments. Automotive technicians and industrial mechanics can also leverage this device to ensure proper ventilation and safe atmospheric conditions within workshops, garages, and enclosed industrial spaces.
