A step-up transformer that allows you to drive fans without the low-frequency sound at low speed.

The six stages of control help to better control the output fan according to the temperature settings you have set.

Two buttons allow setting temperature and temperature hysteresis.
Through the built-in jumper - J1 (in the box) you can choose whether, when the desired temperature is reached, the fan continues to work at minimum speed or stops. When J1 is closed - ventilation continues to work at minimum speed. When open - stops the fan completely.

It is equipped with a 4m cable with a temperature and humidity sensor, an output fan contact and a waterproof case.

- temperature range: 20C° - 30C°
- temperature hysteresis: 2C°-8C°
- size: 265mm x 300mm x 205mm
- max. Power: 2.5A
- Voltage: 230V / 50HZ
- 5V digital sensor measures temperatures from –55°C to +125°C (–67°F to +257°F)
- Accuracy: 0.5C° in an interval from -10C° to +85C°; ±4.5%rh
- Degree of protection: IP54

TechGrow - CO₂ Pressure Reducing Valve the easiest and most effective way to inject CO₂ in the growroom. Connect it to the CO₂-bottle to control the flow of CO₂ in the room. Use in combination with TechGrow - CO₂ Controllers. The product consists of:

• pressure meter
• flow meter
• electric magnetic valve

TechGrow - Temperature Probe Sensor (5m) is the simplest TechGrow sensor that measures temperature. Compatible with various TechGrow devices.

• measures the temperature
• cord length: 5m

TechGrow Sensor Temp/RH  measures temperature, humidity (RH) and detects light simultaneously. These values are shown on the display of your controller. TechGrow Sensor Temp/RH can be connected to various devices. Depending on your TechGrow controller, the sensor will control temperature and/or humidity. The built-in light sensor can be switched off when using a S-2 sensor or a T-Mini CO₂ controller.

TechGrow S-2 CO2 Sensor (2000ppm) measures CO₂ and detects light. It is compatible with all TechGrow controllers. The sensor is equipped with a built-in calibration function so you can calibrate the CO₂ sensor against outdoor air. The calibration menu is only accesible through a CO₂ controller. Also equipped with a built-in switch to prevent unwanted calibration. 

• range: 0 - 2000 ppm

TechGrow S-4 CO2 Sensor (2000ppm) is the all-in-one sensor measures CO₂, temperature, humidity and detects light simultaneously. Also, the sensor is equipped with a built-in calibration function to calibrate the CO₂ sensor against outdoor air. The calibration menu is only accesible through a CO₂ controller. Also equipped with a built-in switch to prevent unwanted calibration.
