Product Description

The HT-1000 Carbon Monoxide Meter is a portable digital instrument for measuring carbon monoxide (CO) concentration in air. It uses a stabilized electrochemical CO-specific sensor and provides readings from 0 to 1000 ppm, with audible indication, Max Hold, data memory and automatic/manual zero functions. 

Product Overview

The Labmart HT-1000 Carbon Monoxide Meter is designed for portable detection and measurement of carbon monoxide concentration in industrial, environmental and inspection applications.

The meter uses an electrochemical sensor specific to carbon monoxide and displays concentration directly in ppm on its LCD. Its combination of fast sampling, manual/automatic zeroing, maximum-value hold, data memory and audible alarm makes it suitable for routine CO monitoring and inspection.

The instrument is particularly useful where a compact handheld CO measurement device is required for checking potentially contaminated environments.

Key Features and Benefits

  • 0–1000 ppm measurement range: Suitable for a broad range of routine CO monitoring applications.
  • Electrochemical CO sensor: Uses a stabilized gas-specific sensor for carbon monoxide detection.
  • 1 ppm resolution: Allows fine-grained display of measured CO concentration.
  • Audible alarm: Provides an alert when CO concentration reaches the specified alarm threshold.
  • Max Hold: Helps capture the highest observed CO concentration during inspection.
  • Auto/manual zero: Provides flexible zeroing for measurement setup.
  • Fast sampling: Supports quick routine measurements.
  • Data memory: Stores up to 10 complete data sets.
  • Backlit LCD: Provides clear digital readings in different working conditions.
  • Portable design: Convenient for field and industrial inspection.
