main features

Using a patented constant temperature device (patent number: ZL. X), the volume resistivity of fire-resistant oil can be directly measured without the need for an additional refrigeration device

Adopting a composite temperature control method combining intelligent fuzzy logic and variable coefficient PID, the temperature control accuracy can reach ± 0.3 ℃

Built in 24 bit ∑ - Δ A/D converter for high-precision measurement of volume resistivity

Fully automatic measurement according to established procedures in both standard and custom modes

■ Historical test data storage and query function

■ Printer: Thermal type, 36 characters, Chinese character output

Reserved RS232 interface, which can transmit test data to the computer through wireless or wired means
