Page 4: Introduction
ES-2 1 INTRODUCTION Introduction METER designed the ES-2 sensor to measure pipe water, tank water (when used with protective cap).A thermistor in thermal contact with the probe provides water temperature, while the screws on the surface of the sensor form a four-electrode array to measure electrical conductivity. -
Page 5: Warranty
This sensor has a 30-day satisfaction guarantee and a one-year war- ranty on parts and labor. Your warranty is automatically validated upon receipt of the instrument. Note: The one year service plan activates when METER ships the instrument and not at the time of purchase. Seller’s Liability... -

Page 8: Measurements
ES-2 3 MEASUREMENTS Measurements Temperature A thermistor near the electrical conductivity (EC) sensor senses the temperature of the water. The sensor uses this temperature to ad- just the EC measurements to their 25 C value, and provides the temperature output for the data stream. -
Page 9: Calibration
4 CALIBRATION ES-2 Calibration METER calibrates our EC sensors at the factory using KC1 solutions of known concentration and calibration values are stored internally in flash memory. The following table relates EC at 25 C to concentration for vari- ous concentrations of KC1. Operators can verify ES-2 performance using these solutions. -
Page 10: Connecting Sensors
Simply plug the 3.5 mm “stereo” connector directly into one of the sensor ports. Figure 1: 3.5 mm Stereo Plug Wiring The next step is to configure your logger port for the ES-2 Sen- sor and set the measurement interval. This may be done using ei-... -

5 CONNECTING SENSORS ES-2 ther ECH O Utility Mobile (see respective manuals). Please check your software version to ensure it supports the ES-2 To upgrade your software to the latest version, please visit METER’s website: www.metergroup.com. The following firmware and software supports the ES-2 Sensor: Em50 Firmware version 2.09 or greater... - Page 12 Scientific Data Loggers, you will need to power the sensors off of the switched 12V port. If your ES-2 Sensor is equipped with the standard 3.5 mm plug, and you wish to connect it to a non-METER data logger, you have two options.
- Page 13 5 CONNECTING SENSORS ES-2 (this type of wire is often referred to as a “pigtail adapter”). Both the stripped and tinned adapter cable wires have the same termina- tion as seen above; the brown wire is excitation, orange is output,...

Page 14: Installation
To integrate the ES-2 into an irrigation pipe, begin by ensuring the white threaded plug is installed on the side of the protective screw cap. Then screw the end of the ES-2 sensor into a 3/4” NPT Tee pipe fitting. If necessary, use a pipe converter to convert from the 3/4”... -
Page 15: Cleaning Method
6 INSTALLATION ES-2 A four electrode conductivity measurement is less sensitive to sensor fouling than a two electrode sensor, but contamination of the elec- trodes can still affect the measurement. The electrodes are stainless steel. Cleaning Method 1. Insert swab into slot on side of sensor housing. Rug the screws vigorously with swab. -
Page 16: Communication
Celsius with a resolution of 0.1 C a carriage return follows the three numbers, then the character “t,” indicating that this is a ES-2 sensor, then a checksum character, and finally a carriage return and line feed. -
Page 17: Common Sdi-12 Commands
Common SDI-12 Commands Table 2 shows common SDI-12 commands that the ES-2 Sensor re- sponds to. The ES-2 can respond to any SDI-12 command under the SDI-12 specification version 1.3. The sensor addresses shown an ‘a.’ If a ‘?’ is substituted for ‘a’ all addresses respond. -
Page 18: Power
Power The ES-2 can be powered using any voltage from 3.6 to 15 VDC, but 12 V is optimal. Although SDI-12 protocol allows the sensors to be continuously powered, it is often best to connect the power wire (brown) to a switched source. -
Page 19: Troubleshooting
2. Verify that your data logger batteries are not dead or weakened. 3. Check the configuration of your data logger in ECH O Utility or DataTrac to make sure you have selected the ES-2 sensor on the correct port. 4. Verify that you are using the most up to date software and firmware. -
