In the heater-equipped version, the heater automatically operates around +4°C to eliminate residual snow and ice even in low environmental temperatures or during/after snowfall. ■ The power supply voltage is DC24V (HD2015R) or DC12V (HD2015R1), with a power consumption of approximately 75W. ■ The measured rainfall is based on the number of times the tipping bucket empties: (1) A collection cone connected to an aluminum cylinder directs rainwater into the tipping bucket. (2) When the specified level is reached, the accurately calibrated tipping bucket rotates under its own weight to drain the rainwater. (3) During the rotation of the bucket, a normally closed reed contact opens momentarily, sending a pulse signal to the counter. * The number of pulse signals is detected and recorded by data loggers or pulse counters such as the HD2013-DB. ▲ Rain, snow, and ice measurements are possible with the heater-equipped models (HD2015R/R1). ▲ Resolution per pulse can be selected as 0.1mm/0.2mm (standard)/0.5mm. ▲ Bird deterrent spikes and wireless loggers for cloud connectivity are also available as options.

Compressed air is used in various fields and for different purposes, and in many cases, low humidity levels of compressed air are required. Therefore, it is necessary to know the dew point temperature (DP) of the water vapor in the compressed air circulating in the system. The HP480 probe is designed for this dew point temperature measurement. Dew point measurement for moisture control in compressed air distribution systems brings many advantages, such as: - Prevention of corrosion in metal pipes - Prevention of ice formation in pipes that can cause blockages in low-temperature areas - Prevention of bacterial growth in medical plants - Reduction of maintenance costs through proper lubrication of moving parts in pneumatic equipment - Improvement of product quality in air-contact products, such as in pellet drying processes ▲ High-precision dew point temperature (DP) measurement ▲ Compatible probe ▲ Quick coupling/thread connection ▲ Measurement chamber material AISI304

In the face of the global pandemic threat posed by the novel coronavirus (COVID-19), many researchers are focusing on discovering and inventing solutions and means to combat the virus. The efficacy of UV lamps is one of the methods to suppress the virus. Recent studies suggest that the application of UVC radiation from new LED lamps is extremely effective. As a result, there has been a remarkable increase in demand for ultraviolet light sources peaked at wavelengths of 265 to 275 nm, which have the highest sterilization efficiency in the market. ▲ Accurate measurement for managing ultraviolet radiation levels ▲ Optimal probe design for LED light sources ▲ Wider spectral range than conventional UVC probes ▲ Accuracy assurance ▲ Probes come with ISO17025 calibration certificates ▲ Easy operation for accurate and safe UV measurement ▲ Portable, durable, and comfortable to hold body
