Instrumentation

The CO₂ Gas Analyzer is a precision instrument designed for real-time monitoring and analysis of carbon dioxide concentration in ambient air. Utilizing a robust infrared (IR) sensor, it offers a measurement range of 0–5% v/v, making it ideal for applications requiring high sensitivity and accuracy.

Equipped with an in-built air sampling pump, the analyzer ensures continuous and reliable gas intake. The device also features a real-time digital display for CO₂ concentration and temperature, along with an integrated datalogger that records values with averaging capabilities. It is built with IP65/67-rated protection, ensuring durability against dust and water ingress, suitable for both indoor and outdoor use.

Its compact design and non-rechargeable 1-year battery allow for maintenance-free operation in long-term or portable deployments.

A handy, portable sound source for calibration of sound level meters and other sound measurement equipment. The calibrator is very robust and stable, and conforms to EN/IEC 60942 Class LS and Class 1, and ANSI S1.40-1984. For maximum confidence in your measurement results you can quickly compensate for local measurement conditions by calibrating before every measurement. Twin sound pressure levels guarantee definitive checks even in noisy environments, and ensure linearity in your microphones.
