Q45C2 2E Resistivity Transmitter
Brand: Analytical Technology IncSpecifically designed for use in ultra-pure water and non-fouling applications, ATi’s Q45C2 2E Resistivity Transmitter provides reliable and accurate low-level measurements for high-purity water systems.
The 2-Electrode sensors are available in several mounting configurations, including 316SS compression fittings or sanitary-style.
For applications where results in resistivity units are preferred, the Q45C2 2E can be programmed to display readings in Meg-ohm units instead of microSiemens.
The transmitter employs 2-Electrode conductivity sensors with low cell constants to provide continuous water quality measurements from 0-20 to 0-2,000 microSiemens.
These sensors may also be mounted submersion-style or in a hot-tap configuration.
Features- Concentration version for direct display of chemical concentrations. Also available in a TDS (Total Dissolved Solids) version. Customized Response:
- A user configurable table for a custom concentration curve is available. Analog Output Options:
- Two isolated 4-20 mA outputs are standard. Default setting provides Analog outputs for conductivity and temperature. AC or DC Power Options:
- Power options include 115/230 Vac. PID Output:
- Standard PID control function assignable to one Analog output. Relay Contacts:
- Two SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Flexible Mounting:
- NEMA 4X (IP-66) enclosure is suitable for wall, pipe or panel mounting. Clear Display:
- Back-lit large LCD display provides clear visibility in any lighting condition. A scrolling second line on the display provides additional information and programming prompts.
