HIGH ACCURACY OUTSIDE HUMIDITY/TEMPERATURE TRANSMITTER

HAHTOS SERIES

PRODUCT DESCRIPTION

The HAHTOS series uses a highly accurate and

reliable Thermoset Polymer based capacitance

humidity sensor and Platinum RTD temperature

sensor together with state-of-the-art digital

linearization and temperature compensated

circuitry to monitor humidity levels. A hinged,

gasketed weatherproof Polycarbonate enclosure

provides easy of installation and protection from

the elements.

TYPICAL INSTALLATION

For complete installation and wiring details,

please refer to the product installation

instructions.

The HAHTOS should be mounted on an outside

North facing wall, under the eaves which will

provide protection from direct sunlight and wind.

The HAHTOS can be mounted directly to the

building’s wall face using the two provided

mounting tabs. There is a 0.85” hole for conduit

connection on the rear of the enclosure.
