Introduction: Water activity mainly responds to the balance of the food free moisture, the stability of the reaction food and the possibility of microbial propagation, as well as changes in food quality can cause chemical, enzymatic and physical changes, often used to measure microbial endurance to dryness Ability. By measuring the water activity of food, choose a reasonable packaging and storage methods, you can reduce the use of preservatives, you can determine the food, food, fruits and vegetables shelf life. HD Series intelligent moisture activity meter adopts WSC-4 high-precision sensor, professional circuit design, stable and reliable work; reasonable structure design, easier operation, to solve the problem of inconvenient operation, easy to turn over liquid; calibration, measurement Time only 10 minutes; a calibration, no longer need repeated calibration within a long period of time; using bright LCD display, Chinese characters display more content; with print function, more convenient to record and compare; HD-3A single point measurement, 4 can be measured at the same time four points. Specifications: 1 working environment: temperature 0 ℃ ~ 50 ℃ humidity 0 ~ 85% RH 2 output mode: micro-printer 3 Display: Large LCD 128 × 64 DOTS 4 measuring range: temperature 0 ~ 50 ℃ activity 0 ~ 0.980 5 Measurement accuracy: Temperature ± 0.5 ℃ Activity ± 0.015 (@ 25 ℃) 6 activity repeatability: ≤ 0.015 7 temperature coefficient: ≤ 0.0005 / ℃ 8 Measurement points: 1 ~ 4 points 9 wheel speed: 3 seconds / point 10 print function: ① measuring the end of print ② real-time printing 11 Supply voltage: 220VAC ± 10% 12 Power consumption: less than 15W 13 Dimensions: 320mm × 120mm × 360mm 14 Packing: portable aluminum box
