Biopharmaceutical high-temperature fermentation PH meter

PHG-2091A type high temperature PH meter Industrial PH meter is one of the 2091 series intelligent online chemical analyzer developed by our company, with strong environmental adaptability, clear display, simple operation and excellent test performance, which makes it have a high cost performance, and can accurately measure the PH value and temperature
of the solution.

It can be widely used in continuous monitoring
of PH value in solutions such as thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water.

This instrument is dedicated to the PH value measurement of high temperature fermentation, for the bioreactor special PH measuring instrument, can withstand 130 degrees of high temperature sterilization has been in the field of high temperature fermentation measurement PH and dissolved oxygen, are the use of imported instruments, METTLER, Hamilton, E + H and other instruments, and 80% of the products on the market are occupied by METTLER products, domestic high temperature fermentation PH meter has not been recognized by the market, but with the development of domestic technology in recent years, in the field of high temperature fermentation PH measurement , domestic instruments and electrode technology has a qualitative leap, and imported instrument measurement batch is almost no difference, our manufacturers do better than imported products
.

Advantages of high temperature PH meter: microcomputerization: the use of high-performance CPU chip, high-precision AD conversion technology and SMT chip technology, to complete multi-parameter measurement, temperature automatic compensation, automatic range conversion, instrument self-test, high precision, good
repeatability.

High reliability: Single board structure, only one circuit board, no complex function switches, adjustment knobs and potentiometers
.

Strong anti-interference: The current output and alarm relay adopt optoelectronic coupling isolation technology, which has strong anti-interference ability and realizes remote transmission
.

Automatic alarm function: alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm lag revocation
.

Network function: isolated current output and RS485 or 232 communication interface; The current corresponds to the upper and lower limits
of the output of the PH value.

Automatic conversion of the PH value of the standard solution: The temperature curve of the standard liquid is pre-stored, and the PH value of the standard liquid at the set temperature is automatically converted during the calibration to automatically identify the wrong calibration: If the user incorrectly uses the standard buffer at the calibration, the instrument will automatically prompt it

Secondary table installation mode: open hole type; Electrode installation mode: flow-through, sinking, flange, pipeline high temperature fermentation measurement of PH value and dissolved oxygen value is the usual measurement of PH and dissolved oxygen is different, so in the instrument selection must also choose high temperature fermentation special PH meter and dissolved oxygen meter This high temperature fermentation special PH meter can be compatible with a variety of imported electrodes: METTLER, Hamilton, E + H, etc.
, the instrument can be matched with them, our company produces high temperature fermentation special PH electrode can also be matched with their instrument, and, Our company's high temperature fermentation PH electrode sheath is also interchangeable, completely replacing imported products, cost-effective
