A. Product Overview
The R-Tek RT-8716 Digital Psychrometer is designed for simultaneous measurement and evaluation of temperature and humidity related parameters. It measures relative humidity from 0 to 100 percent RH and internal temperature from -20°C to 50°C.
The instrument can display several combinations of measurements, including:
- Humidity and T1
- Humidity and T2
- Humidity and T1 minus T2
- Humidity and dew point
- Humidity and wet bulb temperature
- Humidity and external temperature T2 with dew point
- Humidity and dew point with Delta T, calculated as T2 minus dew point

B. Working Principle
The RT-8716 Digital Psychrometer measures ambient temperature and relative humidity through its internal sensing system. Using these measured values, the instrument provides calculated environmental parameters such as dew point and wet bulb temperature.
An external temperature probe can also be connected for T2 measurement. This enables the meter to compare internal or ambient measurements with an external temperature measurement and display combinations such as T1 minus T2 and T2 minus dew point.
In practical terms:
Temperature and humidity measurement → internal calculation → wet bulb, dew point and temperature difference displayed
This allows multiple environmental conditions to be evaluated using one handheld instrument.
C. Why Is the R-Tek RT-8716 Used?
The RT-8716 is useful when temperature alone is not sufficient to understand environmental conditions. Relative humidity, dew point and wet bulb temperature can provide additional information about moisture conditions in the surrounding air.
The instrument is particularly useful for applications requiring:
- Temperature measurement
- Relative humidity measurement
- Dew point measurement
- Wet bulb temperature measurement
- External temperature measurement
- Comparison between two temperature measurements
- Temperature and humidity monitoring
- Environmental condition assessment
Its 0 to 100 percent RH measurement range, multiple display combinations and portable battery powered construction make it suitable for field measurements as well as routine environmental inspections.
D. Suitable Buyers
Based on the parameters measured by the RT-8716, it can be relevant for buyers involved in:
- HVAC installation and servicing
- Air conditioning maintenance
- Ventilation system inspection
- Environmental monitoring
- Industrial maintenance
- Facility management
- Laboratory environmental monitoring
- Warehouses and storage facilities
- Building maintenance
- Temperature and humidity inspection
- Quality control departments
- Technical service companies
- Instrumentation professionals
These applications are practical use cases inferred from the temperature, humidity, dew point and wet bulb measurement capabilities specified by R-Tek.
