Handheld digital TDS meter (pen type)

Overview:

The TDS handheld meter is a compact digital pen for checking the total dissolved solids (TDS) in water. It gives a quick ppm (mg/L) reading on a clear LCD, so it is a simple way to check drinking water and see how well an RO or filter system is performing. Two buttons keep it easy to use: ON/OFF and HOLD. A removable protective cap covers the probe when not in use.

Key Features:

Quick, Easy Readings
Switch on, dip the probe into the water, stir gently and read the value on the LCD.

Hold Function
Freezes the reading so you can take the meter out of the water and record the result.

Wide Measuring Range
Reads from 0 to 9990 ppm, covering RO permeate through to high-TDS water.

Auto Shut-Off
Turns itself off after about 10 minutes of inactivity to save battery.

Compact Pen Design
Slim, lightweight body that is easy to carry, with a protective cap over the probe.

Technical Specifications:

Compatible Items:

• Suitable for testing drinking water, RO and filtered water, aquariums, pools and hydroponics
• Replacement batteries: 2 × 1.5 V button cells (LR44 type)

Applications:

The TDS meter is suited to:

• Checking RO system and water filter performance (comparing feed and product water)
• Testing drinking and tap water quality
• Aquariums, pools and hydroponic nutrient solutions
• Quick spot checks in home and workshop use

Please note:

• This meter measures TDS only. It does not identify specific contaminants or show whether water is safe to drink.
• Rinse the probe with clean water after use and keep it clean, as dirty electrodes give inaccurate readings.
• Replace the batteries if the display is faint or the meter will not turn on.
• Do not submerge past the water level limit, and keep the electronics end dry.
• Replace the protective cap after use.
