On-off controller
The HG120 serves as an on-off controller for regulating relative air humidity. It’s suitable for controlling air humidifiers and dehumidifiers in various environments, including offices, computer rooms, food storage, cooling rooms, greenhouses, textiles, printing, film production, and healthcare facilities.
Remarkably straightforward and durable design
Our Humidistats feature a simple and robust design. The Polyga® measuring element is a unique hygroscopic fibre that changes its length depending on the humidity. The changes in length of the POLYGA® fibres are transferred via a lever system to a microswitch, resulting in an on/off controller that needs no auxiliary power supply.
Waterresistent and maintenance-free
It has unparalleled long-term stability and is 100 % waterproof, which makes it ideal for use in high humidity. In pure ambient air the measurement element is maintenance-free.
Internal scale and adjusting knob
The HG Mini-i version was designed so that the control knob and scale are inside the housing. This makes unauthorized adjustments more difficult.
POLYGA® transmitters demonstrate excellent measuring properties and accuracy in high humidity. They can be adjusted and cleaned in water. Their outstanding durability, reliability and robustness make them the classic choice for applications with extended high humidity.
Remarkably straightforward and durable design
The Polyga® measuring element is a unique hygroscopic fibre that changes its length depending on the humidity. The changes in the length are converted into electrical resistance values that can either be directly measured (passive transmitters) or converted further into standard analogue output signals (active transmitters).
Waterresistent and maintenance-free
It has unparalleled long-term stability and is 100 % waterproof, which makes it ideal for use in high humidity. In pure ambient air the measurement element is maintenance-free.
