Introduction
The YOCO VIS-722S Visible Spectrophotometer is an economical analytical instrument with optional RS232 interface output. Excellent metering accuracy is higher than that of general instruments of the same grade, and is widely used in many fields such as testing, food, petrochemical industry, environmental protection and monitoring.
Features
1. Digital display of measured values
2. Automatic light door, automatic zero adjustment and 100 instrument calibration
3. The original imported tungsten lamp is used to ensure the service life of the instrument
4. Large sample chamber, up to 10cm cuvette
5. The optional output port RS232 can realize the function of connecting to the printer and connecting to the computer
Button function
Key name: Description of the function of the key
【MODE】A/T/C/F mode switch key
[PC] Print/send data key online
【↑/0%】C/F mode input data becomes larger/adjust 0%T key
【↓/100%】C/F mode: input data becomes smaller/adjust transmittance to 100%T or absorbance 0.000ABS key
Description of the function of the button
A: Measure the absorbance of the sample
T: Measure the transmittance of the sample
C: Enter the F-number to measure the concentration, or calculate the F-number with the standard solution
F: Enter the F-value to measure the concentration
