PHS - gn20-3b / 3C / 2C / 25 type acidity meter

3B, pHS - pHS - 3C belongs to the general-purpose acidity plan, pHS - 2C belong to economical acidity meter, pHS - 25 belong to simple type acidity plan, are a common market, on the basis of model in intelligent, measuring sex, use of the environment as well as its physical structure, the higher substantially improve ratio. Can be widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemical, food and water and other solution pH value of continuous monitoring.

Technical indicators

Showing the way: double row digital tube (pHS - 2C, pHS - 25 for single row)

Measuring scope: - 2 ~ 18.00 pH, - 1999 ~ + 1999mV, 0 ~ 99.9 ℃

Points distinguishes rate: 0.01 pH, 0.1 ℃, 0.1 mV

Fine degrees: pHS - gn20-3b, 3C + 0.01 pH, + 1mV, + 0.3 ℃

PHS - 2C + 0.02 pH, + 0.2% FS (mV)

PHS - 25 + 0.05 pH, plus or minus 0.5% FS (mV)

Used scope: the auto/hand-switch 0 ~ 99.9 ℃

Temperature compensation: can the sandhust electrode slope temperature compensation, pure water and add 25 ℃ convert ammonia ultra-pure water

Input impedance: Ω > 1012

Communication interface: RS232 two-way communication

Electricity source: AC220V + 22V, 50Hz 1Hz, external power plus or minus

Working conditions: environmental temperature 0 ~ 60 ℃, relative humidity 90 acuities ℅

> power lost save: five years

Calibration way: a bit of calibration, two calibration

Size, weight: 202x202x68mm, 1.0 Kg

Standard configuration: pHS - XX second table one, HT5 power a T226 two composite electrode, a T22 temperature electrode a (pHS - only to match), electrode 3B stent a set, standard buffer a set.

Main features

Double row digital tube: respectively show pH value/mV and temperature.

Microcomputer: using high-performance the CPU chip, high-precision AD transform technology and SMT placement technology, perform multiple parameters measurement, temperature compensation, instrument self-check and precision, repeatability.

High reliability: veneer structure, touch buttons, no switch knob.

25 ℃ convert: can the sandhust electrode slope temperature compensation, pure water and add 25 ℃ convert ammonia ultra-pure water.

Input impedance Ω > 1012.

Waterproof and erosion design.

Standard fluid temperature automatic conversion: stored the standard fluid temperature curve, calibration automatically converted into a standard set temperatures liquid in the pH.

Automatic discriminant error calibration: if users calibration wrong using standard buffer liquid, instrument will automatically tip.

Network function: RS232 two-way communication, can match a printer or TLab1.0 communication and data processing software.

Industrial control type watchdog: ensure instrument won't crash

An automated measurement destination

4 of the main difference between: 1, precision different 2, pHS - 3C, pHS - 2C, pHS - 25 temperature compensation can only manual input 3, pHS - 2C, pHS - 25 for single digital tube display

Guide: what shall inform the order is the medium, facilitate matching electrodes.
