What's in the Box

Upon opening the package, please verify that all the following items are included:

• 1 x Arendsace 4-in-1 TDS Meter (white)
• 1 x Instruction Manual
• 1 x Color Box
• 2 x LR44 Batteries (pre-installed or included separately)

Product Features

• Accurate and Reliable Readings: Equipped with smart high-precision intelligent chips and high-quality titanium alloy probes for stable and accurate detection.
• 4-in-1 Multi-functionality: Measures Total Dissolved Solids (TDS), Electrical Conductivity (EC), and temperature in both Celsius (℃) and Fahrenheit (℉).
• Intelligent Backlit Display: Features a large, easy-to-read backlit screen, ideal for low-light or dark environments. The screen changes color based on TDS levels: green for values below 40ppm and red for values exceeding 40ppm.
• Automatic Lock Function: Automatically locks detected values, eliminating the need for manual button presses to hold readings.
• Power Saving: Automatically shuts down within 2 minutes of inactivity to conserve battery life.
• Wide Range of Applications: Suitable for testing drinking water purity, checking the efficiency of reverse osmosis (RO)/DI systems, hydroponic nutrient solutions, swimming pools, spas, and general daily water testing.

Setup

1. Battery Installation: The device comes with 2 LR44 batteries included, which may be pre-installed. If not, locate the battery compartment cover at the top of the meter (as shown in the diagram). Carefully remove the cover and insert the batteries, ensuring correct polarity. Replace the cover securely. Note: Some users have reported the battery compartment cover can be tight; gentle prying with a flat, non-abrasive tool may be necessary if it's difficult to open.
2. Protective Cover Removal: Before use, gently pull off the black protective cover from the bottom of the meter to expose the electrodes.
3. Initial Cleaning: It is recommended to rinse the electrode probe with distilled water before the first use to remove any manufacturing residues.

Operating Instructions

1. Prepare Sample: Pour the water sample you wish to test into a clean container.
2. Power On: Press the ON/OFF HOLD button to turn on the meter. The display will illuminate.
3. Immerse Probe: Dip the electrode probe into the water sample, ensuring the water level is between the minimum and maximum water level marks indicated on the meter. Do not immerse the entire meter.
4. Read Measurement: Wait for the reading to stabilize (typically a few seconds). The meter will automatically lock the reading.
5. Switch Modes: Press the MODE button to cycle through the four detection modes:
   • Mode 1: TDS (Total Dissolved Solids) in ppm (parts per million)
   • Mode 2: EC (Electrical Conductivity) in µS/cm (microsiemens per centimeter)
   • Mode 3: Temperature in ℃ (Celsius)
   • Mode 4: Temperature in ℉ (Fahrenheit)

6. Clear Reading: Press the CLEAR button to reset the current reading before taking a new measurement.
7. Backlight Indicator:
   • If the TDS value is below 40ppm, the screen backlight will remain green, indicating ideal drinking water quality (e.g., RO/DI system water).
   • If the TDS value exceeds 40ppm, the screen backlight will turn red, prompting attention to higher dissolved solids.

8. Power Off: The meter will automatically shut off after 2 minutes of inactivity. You can also manually turn it off by pressing and holding the ON/OFF HOLD button.

Maintenance

• Clean Probe: After each use, rinse the electrode probe thoroughly with distilled or purified water to prevent residue buildup.
• Dry Probe: Always dry the probe completely with a soft, clean cloth or tissue after rinsing to ensure accurate readings for future tests.
• Storage: Replace the protective cap over the electrode probe when not in use. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Replacement: If the display becomes dim or the meter does not power on, replace the LR44 batteries.
