![]() ![]() The best way to store the probe is with the probe's cap filled with storage solution or calibiration buffer and the cap tightened to prevent leakage. This will damage the sensitivity of the probe. Storing in pH probe storage solution or pH calibration buffers will help address both these issues. Allowing the probe to dry out may also result in the junction hole getting clogged. Long periods of dry storage will damage the sensitivity of the probe. You can extend the life of your pH electrode in the following ways. If the junction hole gets clogged, the pH probe will no longer function. The reading is generated based on the electrical difference between the sample and reference. The reference junction is a small hole that allows the meter to compare the sample to a reference. The glass bulb loses sensitivity with use and will eventually fail. ![]() The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction. PH meters usually start performing poorly because of problems with the probe. 6.5 feet probe cables for extra flexibility when testing.Gel-filled, double junction MA911B/2 (included) lab grade pH electrode for low maintenance and high performance.Simple two-point pH calibration and one point EC, for increased accuracy with manual trimmers for easy adjustment.External Switch atop the unit converts EC conductivity to EC using 0.5 or 0.7 conversion factor.Fast easy to read current results with 3 large digital BACKLIT LCD readouts.The MC811 MAX pH/EC/Temp Monitor comes with a complete mounting kit including a probe holder. Just calibrate the parameters and begin to monitor 24/7! Easy installation The Milwaukee MAX Monitor offers an accuracy to ± 0.2 pH with two point manual calibration, EC accuracy of ☒% Full Scale and ☐.5 ☏ (0.3 ☌) temperature accuracy. The Milwaukee MAX pH/EC/Temp Monitor offers: Accuracy Common uses are nutrient tanks, Hydroponics and aquariums. The Milwaukee MC811 MAX pH/EC/Temp Monitor is preferred by people looking to know 24/7 what their pH and nutrient levels are on an ongoing basis. Just calibrate the parameters and let the Milwaukee MAX Monitor do the rest. The MC811 MAX Monitor automatically monitors and displays pH/EC/Temp levels. I recommend this to any serious grower." Summary "Using this now, far less expensive than what my friends paid. I can monitor 24/7, point a camera on it and connect to my phone." "I run this unit 24/7 and have not had any problems for the past two months. Why Guard when you can Monitor! The Milwaukee MC811 MAX pH/EC/Temp Monitor lets you monitor your pH/EC/Temp levels 24/7 automatically. Power supplied by the SIM900 Mainframe, or optionally by a user-supplied DC power supply (☑5 V and +5 V).Accurate. Full remote operation is available over the serial interface.Ġ Ω to 1400 Ω (1 mA excitation), 0 Ω to 140 kΩ (10 ♚ excitation). Results are displayed on an easy-to-read, 4-digit LED display. Non-volatile memory also permits storage of a 256-point custom calibration curve to convert sensor units (V or Ω) to temperature units (K). The second (monitor) output is the buffered, low-noise raw sensor voltage without any additional processing.Įither analog output may be coupled to the SIM960 Analog PID Controller for high-performance, closed-loop temperature control.Ī factory-standard calibration curve is pre-programmed for each model. A relative-mode button subtracts the last absolute reading prior to scaling, to provide expanded resolution for temperature deviations. The scaled analog output (☑0 V) produces a voltage proportional to measured temperature, with a full-scale range from 10 K to 1000 K. Measurements are performed at five readings per second. Sensor excitations can be disabled to reduce power dissipation at sensitive cryogenic stages. Measurement results can be displayed in either kelvins or ohms.īoth the SIM922A and SIM923A employ four-wire measurement circuits (±I excitation leads, ±V sense leads), making readings insensitive to series lead resistance. ![]() The current to the sensor can be reversed by the user to test for any offset. Sensor resistance is determined ratiometrically with a half-bridge circuit consisting of the sensor and an internal reference resistor. The SIM923A has selectable 10 ♚ and 1 mA current sources to provide sensor excitation. Results can be displayed in either kelvins or volts. The SIM922A has a programmable, precision 10 ♚ current source to provide sensor excitation. Based on the modular SIM platform, they provide high performance capability in a small footprint. The SIM922A Diode Monitor and the SIM923A RTD Monitor continuously read a single sensor and provide both digital and analog outputs. ![]() SIM922A & SIM923A Diode & Pt RTD Monitors ![]()
