MW803 MAX | 4-in-1 Tester

The MW803 and MW804 are pocket pH pen testers with dual-level LCD that measure pH/ Conductivity/TDS/Temperature in one single tester!

The large display shows readings in an extended range from 0.00 to 14.00 pH and 0 to 3999 μS/cm, 0 to 2000 ppm (MW803), 0 to 20.00 mS/cm, 0 to 10.00 ppt (MW804) and simultaneously shows temperature from 0.0 to 50.0°C or 32.0 to 122.0°F. They have a stability indicator and hold function that freezes the display for easy and accurate recording. The large display also has graphic symbols to guide you through all operations. The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient (β).

Ideal for quick and accurate measurements in swimming pools, aquariums and horticultural applications they can also be used in Industrial and Laboratory applications such as cooling towers, food processing, plating, drinking and waste water etc.

DESIGN FEATURES

• Fast easy to read results with large digital dual LCD readout.
• Extreme accuracy to ±0.05 pH, EC / TDS 2% Full Scale and Temperature ±0.5 C / ±1 F.
• Range 0.00 – 14.00 pH | EC 0 to 3999 uS/cm | TDS 0 - 2000 ppm | Temperature: 0.0 to 50.0 C / 32.0 to 122.0 F.
• Lightweight and portable at just 3.5 ounces.
• Easy measurement: just place the probe in the sample, gently stir, wait for the stability indication to show a stable reading and then freeze the reading.
• Simple push button, automatic 1 or 2 point pH calibration with 5 saved calibration points and simple 1 point EC calibration.
• Gel-filled, double junction pH electrode for low maintenance and high performance with exposed temp. sensor for fast readings.
• Auto shut off after 8 minutes of non-use.
• Fully waterproof to IP65*.
• Battery life approx. 100 hour of continuous use (batteries included).

*An IP65 Rating means the product has the highest level of dust protection, and is able to withstand low-pressure water jets from all directions.
