Relative Humidity and Temperature Indicator/Transmitter with Independent Outputs.
For use with the WDT-DW - Wet & Dry Bulb Humidity Tank.
Wall Mounted Wet & Dry Bulb Humidity Tank.
Commonly used with the IN-HWD (rev 2) - Wet & Dry Bulb Humidity and Temperature Indicator/Transmitter.
The LPN-H is a complete relative humidity and temperature sensing module, with two loop powered 4~20mA output signals,
representing 0~100%RH and 0~100ºC (0~200ºF optional). Now features a Sensirion SHT25 Digital Humidity Sensor!
Available in both Wall and Duct mount models to suit your application.
The LPI-pH is the device to choose when a pH probe is installed in a corrosive, damp, high earth current or electrically noisy environment.
pH and ORP Probes Available - Wedgewood Analytical.
The HT-HR is a small Dual Channel High Resolution (16 bit) Humidity and Temperature data logger. The humidity and temperature sensors are housed in a 60 micron Stainless Steel filter at the top of the logger. The HT-HR (Mk 4) now uses a Sensirion SHT15 digital humidity sensor giving ±2.0%RH accuracy from 10%RH to 90%RH.
The HT-LCD is a handheld humidity data logger with an integral humidity sensor and liquid crystal display. Both Relative Humidity and Dew Point can be displayed and logged. The HT-LCD uses a Sensirion SHT11 digital humidity sensor giving ±3.0%RH accuracy from 20%RH to 80%RH.
The HT-LCD logger is designed for indoor use (IP 40). For outdoor applications, we recommend the THT-LCD housed in a IP66 Weather Proof Enclosure.
The THT-LCD logger is identical to the HT-LCD logger, except that it has an external Humidity/Temperature probe.
There are two external Humidity/Temperature probes available for the THT-LCD (the THT-LCD includes the HT11-Probe):
The HT11-Probe uses a Sensirion SHT11 digital humidity sensor giving ±3.0%RH accuracy from 20%RH to 80%RH.
The HT15-Probe uses a Sensirion SHT15 digital humidity sensor giving ±2.0%RH accuracy from 10%RH to 90%RH.
The probe is connected to a socket on the end plate at the top of the logger. The probe cable is 1.5 meters in length.
The device is used to measure/control the pH value, the Redox tension or for NH3 (ammonia) concentration measurement. The function can be changed directly at the device. Depending on the value to be measured, single-rod electrodes (e.g. pH/Redox single-rod electrodes, gas sensitive probes) or separate versions (glass/metal electrodes with separate reference electrode) can be connected. Temperature measurement is used as the second input value, which can be performed, for instance, with a Pt100/1000. As such, automatic temperature compensation is possible for the pH value and NH3.
Depending on its configuration, the device measures and controls the pH value or the Redox tension in aqueous solutions.
