Item Type: PH Detection Sensor <br>Heating Voltage: 5±0.2V (AC DC) <br>Working Current: 5-10mA <br>Detectable Concentration Range: PH0-14 <br>Detection Temperature Range: 0-100℃ <br>Response Time: ≤5S <br>Stability Time: ≤60S <br>Component Power Consumption: ≤0.5W <br>Operating Temperature: -10~50℃ (nominal temperature 20℃) <br>Working Humidity: 95%RH (nominal humidity 65%RH) <br>Terminal: BNC Connector<br>1、[MAIN PURPOSE] PH value detect sensor module and PH waterproof digital probe kit, mainly used for PH value monitoring and control. <br>2、[APPLICABLE USAGES] BNC connector fits most PH meters and controllers, widely used in aquariums, hydroponics, laboratories, etc. <br>3、[WIDE USE RANGE] The detectable concentration range is PH0?14, which makes the PH value sensor module have a wider application range. <br>4、[HIGH EFFICIENCY] The response time of the sensor sensor is ≤5S, the stabilization time is ≤60S, efficient and convenient in operation. <br>5、[WITH WATERPROOF PROBE] Equipped with digital sensor probe, has good waterproof effect, with dual temperature compensation function.1. Probe cannot be tested continuously for a long time <br>2. If you are using a Particle product like Photon or Argon, be aware of an error. It's a hardware issue with the analog port fluctuating voltage, enough to fluctuate your ph by 0.7 or more at these low voltage readings. To fix this, you'll need to add a 0.1uF capacitor between the analog port you're using and ground.1 x PH Value Sensor Module<p>1 x Digital Probe&nbsp;<br></p>
