- ELIT Electrode Pre-amplifiers will improve the measurement when
the pH/mV Meter or Data Acquisition System has no high-quality amplifier.
- Made from high quality components, these pre-amplifiers have very high input impedance and very low bias current.
- Suitable for any pH, Ion-selective or ORP electrode with BNC connector.
- Easy to install, no power supply necessary.
Specifications
Dimensions: 95 x 55 x 30 mm (Length x Width x Height) including Flange
Mounting: 4 Drill holes with 5 mm Diameter are arranged in an 86 x 38 mm square
Enclosure Material: black ABS. Protection Class: IP 52 (NEMA 2/3)
Connectors for Electrode Input and Output: BNC Sockets, 50 Ohm type
Power Supply: 2 Li-Mn Batteries Type CR2032 provide power for 3 Years
Input Impedance: typical 1 Terra Ohm (1x1012 Ohms)
Input Bias Current: typical 0.1 pA (1x10-13 amps)
Transfer Characteristic: the electrode mV signal is transferred 1:1 to the mV Output
Load Resistance: must be 250 kOhm or higher
Installation
The Sensor Pre-Amplifier can be fixed to any surface using screws of less than 5 mm diameter.
Must be installed in a location where the connectors are not directly exposed to water, chemicals and fine dust.
The cable from the output connector to the measuring system can be a low-cost Coaxial cable of any type.
When no electrode is connected, the input connector should be covered with the supplied 50 Ohm BNC Protection Cap
Maintenance
The Sensor Pre-Amplifier is maintenance-free for 3 Years. After this time a change of Batteries is recommended.
Other ELIT Pre-Amplifiers
Nico2000 have a wide range of Sensor Pre-Amplifiers suitable for other sensor types and longer distances between electrode and measuring system. Versions are also available with alternative output signals (4-20 mA, RS232, RS485) and complete galvanic isolation.
