PTH10 digital temperature and humidity probe can achieve extremely high temperature and humidity measurement accuracy through the multi-point temperature and humidity curve fitting technology. It is used in high-precision temperature and humidity inspection instrument, handheld temperature and humidity instrument and temperature and humidity field instrument, with small thread joint structure and easy to install and maintain.

The humidity-sensitive element of PTH10 is a high molecular film humidity-sensitive capacitor, which is resistant to high humidity and immersible. The temperature compensation and calibration is made in the temperature range of -40 ... 80℃. The internal circuit adopts low power consumption design and temperature drift compensation. The multi-point humidity calibration is carried out in the measuing range of 0~100%RH, and the temperature and humidity measurement accuracy can be up to ±0.2℃&±1%RH.

      PTH10 is available in 316 stainless steel for harsh industrial environment with up to 10m signal cables.

In the applications such as environmental test chamber, biological incubator, biopharmaceutical machinery and handheld temperature and humidity inspection instrument, the installation size of temperature and humidity probe requires miniaturization, and can ensure measurement accuracy and long-term stability in high humidity environments and wide temperature ranges. PTH20 temperature and humidity probe is ideal for these applications.

       The humidity-sensitive element of PTH20 is a high molecular film capacitor, which is resistant to high humidity and immersible. The temperature compensation and calibration is made in the temperature range of -40 ... 80℃, while the VHP filter is optional in the special VHP sterile environment to prevent the measurement drift of the humidity-sentive element. In addition, a variety of signal outputs can be selected: 4 ... 20mA, 0 ... 1V, 0 ... 5V, 0 ... 10V or RS485, etc.

The humidity of environmental test chamber, aging test chamber and other equipments is a very important monitoring parameter. There are extreme high and low temperature and high humidity environment during the operation of equipment, which brings great challenges to humidity measurement. The humidity-sensitive element of PTH40 humidity probe is a high molecular humidity-sensitive capacitor, together with PT1000 temperature-sensitive element, which can provide temperature compensation to ensure accurate measurement.

PTH40 is a split probe-type structure with the split cable length of 2m, the transmitter shell is Aluminum alloy, the sheath material is high temperature resistant PTFE, and the probe operating temperature range can reach -70~180℃. In addition, the probe uses a small package to facilitate to install on the equipment. The probe filter is a fast-responding PTFE filter that resists high temperatures and chemical contamination.
