Introduction: The main technical indicators of this meter/interface tension meter still reach the standard of fully automatic basic type. Except that the test platform of the instrument is changed from automatic lifting to manual lifting (including fast and fine-tuning second gears), the test process is still automatic testing, calculation And display. Under the premise of ensuring technical indicators, it is an economical and practical product. Features: 1. The sensor is sensitive, high precision, LCD display; 2. Automatically read the surface tension balance value; 3. Manual lifting has two speed and fine adjustment gears, which is simple and reliable; 4. One key reset; 5. One-key calibration, with standard weights attached, accurate and fast; 6. The error caused by the instrument itself is small, and various errors in the measurement process can be controlled more effectively; 7. Using platinum plate method or platinum ring method, connected to a computer, optional real-time curve software: Can clearly show the tension rise or fall curve over time due to the presence of surfactants. It can display the curve and time of the tension value of the liquid interface of two different densities from low to large z, such as oil/water interfacial tension value. 8. Optional sample constant temperature cup, external constant temperature bath can control the temperature of the liquid to be measured. technical parameter: Product model BZY-4B Measurement method Platinum plate method (platinum ring method) Test range mN/m 0－200 Tare range mN/m 0－200 Resolution mN/m ±0.01 Standard error mN/m ±0.03 Repeatability ±0.03 Data display LED display Measuring time for low-concentration samples 3-5 seconds Platform lifting manual Platform lifting distance (mm) 16 fast, fine-tuning 18, fine-tuning 0.02 per grid Signal output interface RS232C Real-time curve software standard Sample temperature 0～110℃ Temperature sensor: PT:100 Power supply voltage: AC220V±10% Dimensions (mm): 300×190×400 Net weight (kg): 7
