One, the characteristics and uses: PHB-5 type portable PH, the instrument and the electrode can be separated, with the BNC standard plug connection,. Therefore, the instrument is small in shape, the electrode is easy to change, and the instrument is more reliable.The instrument is suitable for the research of the laboratory, industrial and mining production, agriculture, animal husbandry, environmental protection and water quality supervision.
Two, applicable skills:
1, measurement range: 0-14.OPH
2, level: 0.1
3, liquid crystal display, easy to carry, with E201-C composite electrode
4, PH measurement range: 0.00~14.00pH, measurement accuracy: + / - 0.1pH
5, the scope of temperature compensation: no
6, power: DC 9V battery section (not including)
7, size: 120*40*34mm
8, weight: 110g
Three, the function and position of the instrument appearance and operation button
1, display: (LCD)
2, power switch: (ON/OFF)
3, slope regulator: (SLOPE)
4, positioning regulator: (AP)
5, electrode connecting seat: (BNC)
Four, the use of methods
1, open the back cover into the battery
2, in the BNC socket connection electrode, and turn on the power supply (press the switch)
3, with pure water cleaning electrode and wipe dry, electrodes placed on the PH6.86 standard solution in the, stirring after static place to show the value of stability after using a small screwdriver to adjust the positions of the regulator (AP) that shows the value PH6.86 (25 DEG C). With pure water cleaning clean electrode and wipe dry, the standard solution of (or PH9.18) electrode was placed in the PH4.00, stir after static place display a stable solution, using a small screwdriver adjusting slope regulator (slope) to display the value for PH4.00 (or PH9.18).
4, after correction by pure water and dry cleaning electrode.
5. The electrode is placed in the solution of the test and the static posit
