TDS water quality test pen is used to test the TDS value of water, the conductivity of water, in order to determine who's purity. At the same time, it has the function of testing water temperature and environment temperature, and it can be widely used in water treatment industry, drinking water industry, family, personal home travel, field operation and so on. The platinum electrode design: The EC series of high purity platinum sensor design, in the whole range of the measurement value to ensure accurate and stable. The data lock: The EC series has a simple measurement value lock function, in the conductivity measurement mode, press the HOLD key, the instrument automatically locks the current measurement value, once again button, the instrument returns the measurement mode. Product Features 1. Digital display: accurate to 4 digits. Temperature compensation accurate to 0.1 2. Backlight function: green backlight while TDS value =40,red backlight while TDS value>40. 3. Auto-lock: TDS value stabillizes 4 seconds, instrument automatically lock readings. 4. One Touch function: Forget to turn off the power, automatically shut down after 2 minutes. Product Description EC testing range: 0-9999µs TDS testing range: 0-4999ppm Accuracy: ±2% F.S Battery:CR2032*1 button cell (included) Size: 16.19*2.94*1.59(cm) Operation 1. Remove the protective cap.Press ON/OFF button. 2. Immerse the meter into the water/solution height no more than 4cm(From the beginning of TDS meter). 3. Waiting until the display stabilizes,the TDS Meter automatically compensates for temperature variations Once the readout is stabilized(30-45 seconds). TDS value stabillizes 4 seconds, instrument automatically lock readings. 4. After usage,shake off water from your meter or wipe it with a tissue. Package Inclusion 1 x TDS-EC Meter with Battery 1 x Leather carrying case 1 x English User's manual Note 1. Keep the electrode clean. 2. Do not soak the TDS pen into the water. 3. Always close the electrode protective cap. 4. Please take out the batteries for long periods unused. 5. Though durable, the TDS meter is an electronic instrument and should be treated with proper case and maintainance.
