WAVETEK manufactures both the online and laboratory-type pH analyzer and meters.
pH meter: Model: UNIQUE3000
UNIQUE3000 is a microcontroller based pH indicator with transmitter and controller. It is a popular model for online pH measurement and control in various type of process industries.
Since it is a microcontroller based design, the measurement is very accurate. (Accuracy = 0.01%).
It has 2 relays output that can be used for control applications. The relays can be user configurable for hi-low alarm purpose also. The set points are adjustable with user-settable hysteresis band.
Also, the UNIQUE3000 has 4-20 mA output, which is proportional to the pH value (4-20mA to 0-14 pH). The Output can be used for interfacing any further systems like PLC, data-logging system, jumbo display system, etc.
The instrument has auto/manual temperature compensation facility which removes the measurement errors due to temperature variation.
The calibration of the instrument can be done very easily through tactile key-pad. Since the calibration mode is password protected, any unauthorized access is avoided.
There are two enclosure versions available:
- Panel Type
- Field type(IP65, weather-proof)
Laboratory-Type pH Analyzer - Model MARVEL5000
- MARVEL5000 is a Microcontroller Based Instrument which is suitable for Laboratory Use
- It has Auto /Manual Temperature compensation, hence the difference in measurement due to temperature variation is compensated
- The Key feature of the Instrument is Auto calibration facility. The calibration with a standard buffer solution is done with a single key press
The display can operate in 3 different parameter modes:
- Relative millivolt
By the changing the mode, any of these parameter can be set to measure and display.
The calibration and other setting procedure is made very easy with various display messages. Also, various error messages are displayed on any input errors, which allows self diagnosis.
