Apera Instruments AI213 Waterproof TDS Pocket Tester Kit ±1% Accuracy

Description

Product Overview

The Apera AI213 TDS20 is a compact, waterproof pocket tester designed for professionals who need reliable total dissolved solids (TDS) measurements in the field. Built around a high‑precision conductivity sensor, the device delivers ±1% full‑scale accuracy across a 0‑10,000 ppm range, making it suitable for water quality monitoring, aquaculture, hydroponics, and environmental testing. The instrument features a dual‑display LCD that simultaneously shows temperature (0‑50 °C) and TDS values, reducing the need for separate thermometers. Auto‑calibration is performed with a two‑point buffer recognition system, allowing users to quickly verify accuracy without manual adjustments. The robust housing meets IPX7 water‑resistance standards, ensuring reliable operation even when submerged briefly or exposed to splashes. Powered by four AAA batteries, the tester can operate up to 1,000 hours before replacement, providing long‑term service for remote locations.

Usage

Designed for on‑site applications, the AI213 TDS20 excels in a variety of environments. In agricultural settings, growers can monitor irrigation water to prevent nutrient imbalances that affect crop yield. Aquaculture professionals use the tester to assess pond water quality, ensuring optimal conditions for fish health. Environmental agencies deploy the device for river and lake sampling, quickly detecting contamination events. The waterproof design allows for direct immersion in wells, rain barrels, and portable water containers, while the large LCD remains legible under bright sunlight. The included lanyard and rugged carrying case make it easy to transport between sites, and the auto‑temperature compensation guarantees accurate readings regardless of ambient temperature fluctuations.

FAQ

How often should I recalibrate the AI213 TDS20?

The device automatically prompts you when calibration is required. For most field applications, recalibrating every 30 days or after a significant change in water source is recommended to maintain optimal accuracy.

Can the AI213 measure conductivity directly?

Yes, the tester measures conductivity and converts it to TDS values based on the selected conversion factor. The LCD displays both conductivity (µS/cm) and TDS (ppm) for user convenience.

What is the battery life under typical field use?

Powered by four AAA batteries, the AI213 can operate up to 1,000 hours of continuous use, which translates to several weeks of daily field measurements before replacement is needed.

Is the device compatible with other calibration solutions?

While the included calibration solutions are calibrated for the AI213, the device can accept any standard TDS calibration buffers that fall within the 0‑10,000 ppm range, provided they are properly prepared.

What warranty does Apera offer for this product?

Apera provides a one‑year limited warranty covering manufacturing defects. During this period, any malfunctioning units will be repaired or replaced at no cost to the customer.
