Model: KR-HA30
Product overview
This fuel oil H2S test instrument is designed and manufactured in full accordance with the requirements in the ASTM IP test standard, and it uses the rapid liquid phase extraction method to determine the hydrogen sulfide content of fuel oil in the liquid phase. This equipment is suitable for fuel oil with a kinematic viscosity of not more than 3000 square millimeters per second at 50 degrees (measurement of liquid-phase hydrogen sulfide in marine residual fuel, distillate fuel and petroleum combination), and both methods A and B can be detected. This equipment is divided into heating, host, VPP weather processor, control and other four parts (laptop operation).

Main Features:
This product adopts imported series, computer automatic control, various parameters can be input on the panel, and can realize various control laws such as position control and PID control, High temperature control accuracy, wide application range, and can be used in various occasions that require automatic temperature control. The A method and the B method are interchangeable.
1. The whole machine is treated with electrostatic spray, which is beautiful, generous and easy to clean.
2. Special air pump filter, liquid trap, moisture filter, test tube customized by the company
3. Digital display PID temperature controller, which can be programmed.
4. Three-body structure, plus a laptop (special computer)
5. The instrument A and B are common and can be converted to each other
6. The heating furnace adopts imported double electric furnace wire to work. One group is broken, and the other group continues to work. It is automatically converted and will not be affected during the experiment.
7. The program automatically controls the heating process, and automatically cools down after completion; the temperature section can be set according to the actual situation, which means the heating speed can be adjusted arbitrarily before sampling.
8. Precision flow meter controls gas flow.
9. Imported sensor, high test accuracy.
10. Measurement error: ±1.0%F·S±1b, ±0.5 F·S±1b second gear
