## Description

Package Includes:(Qty 1) Meter Module Control Board(Qty 1) Liquid pH Electrode Sensor Probe with BNC plug (male) termination connectionMeter Module Control Board SpecificationsHeating voltage: 5 ± 0.2V (AC / DC)Working Current: 5-10mADetectable Concentration Range: pH 0-14Detectable Temperature Range: 32 - 176° F (0 - 80° C)Response Time: ≤ 5 secondsSettling Time: ≤ 60 secondsComponent Power: ≤ 0.5 wattsWorking Temperature: 14 - 122° F (nominal temperature 68°F) (-10-50° C (nominal temperature 20° C))Humidity: 95% RH (nominal humidity 65% RH)Module Size: 1.65 x 1.26 x 0.79 Inches (42 × 32 × 20 mm)Output: Analog voltage signal outputModule Mounting: (4) M3 screws (included)Liquid pH Electrode Sensor Probe:The pH electrode sensor probe has a single cylinder that allows direct connection to the input terminal of a pH meter control module. It can be connected and used with any pH device with a BNC input terminal.Features:pH Range: 0-14 pHTemperature range: 32 - 176° F (0 - 80° C)Zero-Point: 7 ± 0.25PHAlkali Error: ≤ 15 mvTheoretical Percentage Slope: ? 98%Internal Resistance: ? 250 MΩResponse Time: ?1 minuteOperating Temperature: 32 - 140° F (0 - 60° C)Termination Connection: BNC plug (male)Note: When using a Particle Photon or Argon, please be aware of a known issue of a fluctuating ghost voltage. Voltage fluctuation can throw off your pH reading by +- 0.7 or more. To fix this, youll need to add a 0.1uF cap between the analog port and ground.

## Features

- Works with any microprocessor control unit (MCU) with GPIO pins, including Arduino, ESP32, and others
- Easy to use and cost effective pH sensor probe, suitable for use with water-based solutions
- pH 7 = approximately 2.51v. pH 4 = approximately 3.03v. Calculating the step, 2.51-3.03 =-0.52. The difference between ph 4.01 and pH 7 is 2.99.
- pH electrode probe must be calibrated with standard buffer solution before each use. Continuous testing for extended periods will shorten the product lifespan.
- There are two trimmers on the circuit board. One of them is for offset adjustment (closest to BNC connector) accomplished by removing the pH probe and shorting the BNC connector with a wire. The other trimmer is an upper limit threshold for the digital output pin.
