More About this Item

The TSI series of portable, handheld, multi-function ventilation test instruments — available with or without a differential pressure sensor — is designed to work with a wide range of plug-in probes. The probes allow you to make various measurements by simply plugging in a different probe that has the features and functions best suited for a particular application. They are designed to measure air velocity, temperature, humidity, CO and CO2. Probes feature a "SMART" plug-in connection that stores all the calibration data, so a new probe can be ordered at any time without the need of recalibrating the meter.

The meter can perform calculations for air flow, heat flow, turbulence, wet bulb and dew point temperature — then data can be downloaded to a PC or portable printer for analysis. Statistics function displays number of recorded samples, average, and Min/Max. Display automatically stabilizes while measuring in fluctuating flow applications. Backlit display allows easy viewing in low-lit areas.
