Vaisala HUMICAPâ Handheld Humidity and Temperature Meter HM70 is designed for

demanding humidity measurements in spot-checking applications. It is also ideal as

an on-site calibrator for Vaisala's fixed humidity instruments.

Vaisala HUMICAPâ technology

HM70 incorporates the world-class

HUMICAPâ sensor, one of the most

reliable and stable sensors on the

market. The HUMICAPâ sensor copes

well with chemical interference and

provides accuracy that lasts in

demanding conditions.

Chemical purge

The chemical purge option maintains

measurement accuracy in environments

with high concentrations of chemicals.

The sensor preheat option reduces

measurement delays as it keeps the

sensor dry when the probe is inserted

into hot and humid processes.

Three probes to choose from

HMP75 is a general purpose probe,

whereas HMP76 is a long, stainless steel

probe especially suitable for spot-

checking in ducts. HMP77 is a small

probe at the end of a 5-meter cable. The

probe is ideal for difficult-to-reach areas

and for on-site calibration of Vaisala's

process transmitters. In addition, HM70

supports the use of Vaisala's dew point,

carbon dioxide, and moisture in oil

probes, allowing measurements in

several multiparameter applications.

MI70 Link Windowsâ software

The optional Vaisala MI70 Link Windowsâ

software and the USB connection cable

form a practical tool for transferring

logged data from HM70 to a PC.
