Photemp C Series Temperature Controllers
Photemp C series temperature controllers are characterized by high accuracy measurement, high adaptability and high power PID output. It is configured with up to 4 PID temperature control loops, and each loop output supports 38W (15Ω heating wire) low noise heater power. The inputs of each loop can be associated with any of the 8 thermometers and are adaptable to virtually all diode and resistance temperature sensors on the market.
Main Features
- Temperature control range: temperature measurement can be as low as 300mK, resolution up to 0.1mK;
- Number of channels: standard configuration 1\4\8-way temperature measurement channels, each temperature measurement channel is independent of each other;
- 4-way PID independent temperature control: 38W * 4
- Can realize continuous measurement and control from 300mK to 500K
- Supports multiple types of diode and resistance type temperature sensors,
- Thermometer excitation current can be adjusted in multiple steps to reduce thermometer self-heating;
- Support USB (serial port), RS485 communication.
- ASCII protocol, compatible with most manufacturers' protocols.
