Thermo Scientific Alpha Process

Thermo Scientific Alpha Transmitters

Approx Price: Rs 1,100 / Onwards 
pH/ORP:

pH/ORP control is easy with the Alpha pH 190 and pH 200 limit controllers. Featuring 6 sub-menus accessible via a four-button keypad for quick, easy setup and calibration, the controller/transmitters also come with two levels of password to protect against unauthorized tampering.

For faster and more convenient control, choose the Alpha pH 190 which allows direct access to the set-point adjustment and calibration menus; for heightened security, use the Alpha pH 200 limit controller which only allows access to calibration and set-up menus via passwords.

Easy push-button calibration with USA/NIST buffer recognition for fast, effortless calibration. Controller freezes data transmission and relay activities during calibration and maintenance.

Features:

  • Symmetrical mode of operation for clear, uninterrupted readings even in electronically noisy environments
  • Two SPDT relays with independent hysteresis – effective high/low set-points limit control with minimal relay-chattering
  • Choice of automatic or manual temperature compensation. Three-wire system compensates error due to cable resistance
  • 85 to 250 VAC. 50/60 Hz or DC variable input allows controller to be used with a wide range of supply voltages
  • Full-scale 4 to 20 mA galvanic ally isolated current output for process control.

  • Item Code: PH-190-200

Thermo Scientific Alpha Controller

Approx Price: Rs 1,400 / Onwards 
pH/ORP:

The Alpha pH 800 and pH 1000 controllers/transmitters combines consistent performance and sophisticated control functions with user-friendly features. Meters come with seven preset buffer values for quick, accurate auto-calibration; electrode offset function allows direct reading corrections without needing to remove electrode from the control system. Alarm delay and individual set-point hysteresis in limit control mode prevent chattering, false alarms, and unnecessary down time.

For finer control, Alpha pH 1000 offers proportional pulse length control and proportional pulse frequency control, in addition to basic limit control.

Features:

  • 2-in-1 controllers/transmitters can be configured to measure either pH or OPR (mV or %)
  • Auto-calibration with choice of NIST or USA buffer selection. Electrode slope and offset is displayed after each successful calibration
  • Symmetrical mode option for clear, uninterrupted pH readings in electronically noisy environment
  • Antimony mode option for use with antimony electrodes in applications that involves corrosive Hydrofluoric Acid
  • Option of Auto or Manual Temperature Compensation. Three-wire system compensates for cable-length resistance errors
  • Galvanic ally-isolated, scalable 0/4 to 20 mA output for high-quality output on peripheral devices
  • Alpha pH 1000 limit/proportional controller also offer two additional features: wash function for scheduled electrode wash, and alarm relay function to alert when measurement crosses the set points
