Overview
The LEICI PHSJ-3F acid alkalinity tester is a smart Benchtop pH meter with a Measurement accuracy of 0.01. Measuring temperature accuracy is 0.1 ° C. It is used for laboratory detection of solution acid alkalinity value and product mass. The instrument adds Electrode performance and calibration reminder function in accuracy design, improves measurement accuracy, and provides Smart, Timed, Cont three reading functions. In addition, it can not only measure PH value, but also Measuring temperature value and mv value, with versatility and wide applicability.
Features
1. Three reading mode functions: Smart-Read mode intelligently judges the end point, which is convenient for reading; Timed-Read mode automatically stores data at regular intervals; Cont-Read mode realizes continuous measurement at intervals to understand the continuous change process of samples.
2. Electrode performance and calibration reminder function, accurate measurement.
3. The measurement information conforms to the GLP specification, and the measurement information can be completely traced back: set the operator number to record the operation process; record the reference and print the calibration data; the measurement data is consulted, deleted, printed and stored; Data storage up to 500 sets.
4. Large screen point array LCD display Measured value, Temperature value, Measurement mode, Electrode slope, equal potential value, operation time and date, the content is clear and comprehensive.
5. Automatic calibration, automatic temperature compensation, automatic identification of 5 kinds of buffer solutions, support 1-3 point calibrating.
6.3 equal potential point selection, simple measurement of pure water, boiler water, ultrapure water and other PH value.
7. The PC panel is made of new materials and features a touch digital keyboard, making it durable.
8. High data security, power failure protection.
9. USB Communication interface and REX data collection software are available.
10. Chinese Operating interface, man-machine interface design is good.
Principle
The alkalinity tester detects the potential change of the solution by Electrode and converts it into pH value, temperature value and mV value. The instrument adopts Automatic calibration and temperature compensation technology, combined with intelligent reading mode, to ensure Measurement accuracy and Stability.
Applications
Laboratory testing solution acid alkalinity value, determination of product mass
Standards
GLP specification
Steps
1. Power on and select the reading mode (Smart, Timed, or Cont).
2. Automatic calibration, can choose 1-3 point calibrating.
3. Electrode is immersed in the solution to be tested, and the instrument automatically measures PH value, temperature value and mv value.
4. Data is automatically stored or manually operated, allowing for viewing, deletion, and printing.
5. Use the USB interface to connect to the computer and perform data collection through REX software.
Notice
• Electrode performance is good, regular calibration reminder check.
• Before use, confirm that the Power Adapter input is AC100~ 240V, and the output is DC9V.
• Avoid use in environments beyond the Temperature range (-5.0~ 110.0) ° C.
• Pay attention to the data storage capacity when operating, up to 500 sets of data can be stored.
• Keep the PC panel clean and avoid scratching the touch keyboard with hard objects.
