PHS - 828/818 JingMiXing acidity meter

PHS - 828, pHS - 818 this is available on the strongest function, use one of the most convenient acidity meter. In intelligent, measuring sex, use of the environment as well as its physical structure, the improved dramatically instrumentation precision is high. 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 respectively show pH value/mV values and temperature

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

Points distinguishes rate: 0.001 pH / 0.01 pH, 0.1 ℃, 0.1 mV

Fine degrees: + 0.005 pH, + 0.2 mV, + 0.3 ℃

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 - 818/828 second table one, HT5 power a T226 two composite electrode, a T22 temperature electrode a (pHS - only to match), electrode 828 stent a set, standard buffer a set.

Main features

Double row digital tube respectively show pH value/mV values 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

TLab1.0 software display instrument parameters, measured value and curve

The difference between the two paragraph pHS - 818 temperature compensation can only manual input

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