IQTT-S Industrial Temperature Transmitter Digital Display Sensor 4-20mA
IQTT-S is a popular Industrial Temperature Transmitter with Digital Display and uses platinum thermal resistance. It can directly measure the temperature of liquid, steam, gaseous media, and the temperature of solid surfaces in the production process within the range of -200°C to 1300°C. Products have been widely used in petroleum, chemical, pharmaceutical, electric power, metallurgy, paper-making, and other industries.
IQTT-S offers a 2 Wire 4-20mA Digital Display Temperature Transmitter and is composed of a thermal resistance (couple) and a protective metal shell.

Recommendation
- PT100 is recommended for applications with a long-term temperature range of less than 300℃.
- When the measuring range is small, PT1000 can be a good choice.
- The k-type thermocouple is recommended if the long-term temperature is higher than 300℃ and lower than 800℃.
- An S-type thermocouple is recommended if the long-term temperature is higher than about 1200℃
