ASTM D974 Auto Diesel Oil Acid Analyzer RGB Color Sensor 0.001 ～ 2.0mgKOH/G

Testing the acidity of diesel, transformer oil and turbine oil is a critical quality‑control step for power utilities, petroleum refineries, commodity‑inspection agencies and research laboratories. Excessive acidity will accelerate equipment corrosion and shorten service life of lubricating and insulating oil.

The SH108B Automatic Diesel Oil Acidity Tester is purpose‑built for acidity & acid‑value measurement of petroleum products. Built to multiple Chinese national standards and ASTM international standards, it automates temperature control, titration, endpoint detection, result printing and waste‑liquid handling to minimize manual operation error.

This instrument is designed and manufactured in compliance with both domestic and global test standards:

• GB/T 264‑1983: Determination of acid value of petroleum products
• GB/T 7599‑1987: Determination of acid value of transformer oil and turbine oil in operation (BTB)
• GB/T 258: Test method for acidity of gasoline, kerosene, diesel oil
• GB/T 4945
• ASTM D974

Practical tip for buyers: When you import lab test instruments, confirm standard compliance in advance for local registration and laboratory audit requirements.

The SH108B adopts a 7‑inch TFT true‑color touch screen with graphic‑text human‑machine interface, operated under a new‑generation intelligent system powered by a 32‑bit microprocessor main control chip.

• ✅ Full‑automatic acid titration: Automatic color endpoint identification, programmable heating bath with auto boiling reflux following reflux‑method test requirements.
• ✅ One‑click post‑test processing: Automatic waste‑liquid draining and reaction‑bottle cleaning after finishing each test.
• ✅ Data storage & output: Stores up to 50 groups of historical records; supports searching and printing via the built‑in 58 mm thermal mini‑printer.
• ✅ High‑precision RGB color sensor: Guarantees stable judgment of titration color endpoint.
• ✅ Light‑weight compact unit: Nice appearance, durable mechanical structure, equipped with high‑accuracy perpetual calendar clock.

Note: Appearance, dimensions, volume and weight are subject to change for product upgrade without prior notice.
