In the field of constant temperature and humidity laboratories, with increasingly strict requirements for quality control, the demand for constant temperature and humidity environments is growing, and the application areas are also becoming wider. Laboratory air conditioning is the heart of temperature and humidity control, requiring high precision and low failure rate.

Constant temperature and humidity test：

Specification and model: LRHS-025-SGD/BJYSL-DHS-100

Temperature range: RT+10 ℃~+100 ℃

Humidity range: 85% to 98% RH

Temperature uniformity: ± 2 ℃ (when unloaded)

Humidity uniformity: ± 3% RH

Temperature fluctuation: ± 0.5 ℃ (when unloaded)

Humidity fluctuation: ± 0.5%

Temperature deviation: ± 2 ℃

Humidity deviation: ± 2%

Standard laboratory configuration

Test hole: Install ø 50mm on the left side of the machine for external testing of power or signal lines (hole diameter and number need to be specified separately before ordering)

The box cover is shared with the salt spray corrosion test box

The test chamber can perform salt spray test and constant temperature and humidity test separately, with conversion function and no interference with each other

Suitable sized liquid soaking tanks can also be placed inside the box

The experimental method is a vertical two box type, with a high-power linear motor used at the top to perform vertical linear conversion through a controller

The conversion time between the high-temperature box and the salt spray box is about 10 seconds

Both upper and lower heights are equipped with limited position photoelectric switches

The sealing between the upper and lower layers adopts a baffle type sealing method, that is, when the sample enters or exits the salt spray box or high temperature box, the middle baffle will automatically fall down to ensure the sealing between the upper and lower layers

Temperature recovery time less than 5 minutes

Place a salt immersion tank of a size specified by the user inside the box, with a temperature range of 30 ℃ to 50 ℃. The temperature can be adjusted and displayed by a real-time temperature controller. The PT100 platinum resistance temperature sensor is used for temperature measurement

The salt liquid refrigeration system adopts a coil cooling method
