3. Main features:

◎ Adopts high-definition LCD screen, users can enjoy intelligent operation with prompts on the screen, and each operation process is provided with Chinese prompts and quantitative indicators.

◎ Powerful data processing capability, which can automatically submit parameters such as the average value, final value or peak value of the tested gel samples.

◎ Provides 4 sampling and measurement modes: single step, hold, cycle, and automatic, making operation more flexible.

◎ The automatic measurement mode can help you obtain the gel strength value faster, more accurately and closer to the actual value.

◎ Provides 5 sampling speeds: 0.1mm/s, 0.2mm/s, 0.5mm/s, 1mm/s, 2mm/s. Selecting high-speed measurement will not cause depth error of the probe pressing into the gel surface.

◎ Sampling depth can be preset arbitrarily (1mm--60mm).

◎ The instrument provides 2 types of sampling results, combined with different test combinations of sampling speed and sampling mode, to submit either the final value or the peak value to users.

◎ Professional high-precision pressure sensor.

◎ High-precision mechanical transmission with 4-level shockproof design.

◎ Users can verify the measurement accuracy of the instrument by themselves (using standard weights).

◎ Automatically corrects nonlinear errors, automatically diagnoses and alarms faults, automatically protects against overrange, and automatically prompts for error correction.

◎ Embedded micro printer, standard serial printing, convenient for storing experimental data.

II. Constant Temperature Water Bath and Refrigerator

1. Technical specifications:

● Water bath temperature control range (5～65.0)℃

● Water bath temperature control accuracy ±0.1℃

● Cooling time (30℃→10℃) <40min

● Power supply 220V/50Hz/1200W

● External dimensions 0634B-1 (58×44×22) cm³

0634B-2 (48×38×29) cm³

2. Main features:

● The constant temperature water bath and refrigerator form a precision constant temperature cold water bath system.

● Adopts magnetic pump circulating water flow homogenization heating system, ensuring uniform water bath temperature.

● High-precision temperature sensor, with small linear error and high measurement accuracy.

● Fully automatic frequency conversion control technology, intelligent temperature control, high temperature control accuracy.

● The refrigerator uses a high-reliability high-power new compressor for cooling, with fast cooling speed and low noise.

● Temperature can be preset arbitrarily; preset value and real-time value are displayed in a time-sharing manner.

● Automation, automatic detection, automatic diagnosis, automatic alarm.

● The inner liner of the constant temperature water bath is made of high-quality stainless steel, with a wide temperature control range and beautiful appearance.

III. Test Method

Take 1.0g of this product, accurately weigh it, add 90ml of water, dissolve it in a 90℃ water bath, then add 1ml of 0.6mol/L calcium chloride solution and 9ml of water, mix well, place in sample bottle A (try to avoid bubbles), tightly stopper with a rubber stopper, and leave it at 20℃ overnight; remove the rubber stopper from the sample bottle, use a probe with a diameter of 12.7mm, at a downward speed of 1.0mm per second, read the reading generated when the probe is pressed down to 6mm below the gel surface, and that's it.
