Product Description
Purpose
The instrument is designed and made as per DL421-91. It is used to determine volume resistivity of insulating oil and other liquid medium. It can also be used to determine volume resistivity of fire resistant oil and solid substance. For fire resistant oil and other low temperature samples, the instrument is equipped with refrigeration device, so that it can change between high temperature and low temperature automatically. Thereby the bath temperature can be controlled to below 10 degree. LCD display, intelligent and automatic temperature control, automatic measurement and the determination procedure can be done automatically. The instrument is composed of measurement oil cup, and heating and temperature controlling system.

Technical parameters
1. Measurement voltage: 500 V, DC;
2. Measurement range: 107~1013 Ω @cm;
3. Repeatability:
(1) P2× 1012 Ω @cm>1: 25%;
(2) P2× 1012 Ω @cm≤ 1: 15%
4. Heating and temperature controlling range: 300 W;
5. Temperature controlling range: Ambient temperature~100degree;
6. Temperature controlling accuracy: ± 0.5degree;
7. Measurement electrode cup: 4 pieces (3 pieces are for high temperature, and the other 1 is for low temperature);
