Product Overview
Monitoring total dissolved solids (TDS) and mineral concentration is critical for maintaining stable water parameters for delicate dwarf shrimp, remineralized reverse osmosis (RO) water, and planted aquariums. The Chihiros TDS Meter is a compact digital water quality tester engineered to deliver fast, highly accurate total dissolved solids readings by measuring electrical conductivity.
Key Features & Benefits
- Instant Digital Accuracy: Measures electrical conductivity to give real-time PPM (parts per million) readings of dissolved salts, minerals, and metals.
- Essential for RO Water Remineralization: Perfect for checking purified reverse osmosis water after adding mineral salts to reach exact GH/KH targets.
- Simple One-Touch Operation: Submerge the titanium alloy probe into water for instant, reliable readouts on the clear LCD screen.
- Compact & Portable Pen Design: Lightweight, pen-style footprint fits comfortably in your pocket or maintenance toolkit for quick spot-checks.

Frequently Asked Questions
1. Are batteries included with the Chihiros TDS Meter?
No. The Chihiros TDS Meter requires 2x LR44 coin cell batteries, which are sold separately.
2. Why is measuring TDS important for freshwater aquariums?
TDS measures the overall concentration of dissolved minerals, salts, and organic compounds in your water column. Monitoring TDS prevents mineral build-up over time and ensures you remineralize RO water to the exact safety thresholds required for delicate dwarf shrimp and plants.
3. Does a TDS meter measure pH or GH/KH directly?
No. A TDS meter measures total dissolved solids based on electrical conductivity in PPM. While it reflects overall mineral content (which correlates to general hardness), dedicated test kits or meters are required for precise pH, GH, and KH values.

Chihiros TDS meter
"Nice meter. Very easy to use and to read. Makes it easy to keep your maintenance going correctly."
Battery mystery solved!
"The description says batteries not included, which is not normally a problem. However the instruction insert fails to give the battery size needed beyond a generic "2 x 1.5V (Button Cell)". Some research led to 357/303 batteries which fit. Otherwise, the device works and the instructions are understandable enough to operate once you overcome the battery mystery. If the description had said the required battery size I would have given it a higher rating. The following sizes are compatible, 357, 303, A76, AG13, EXP76, LR1154, LR44, SR44SW/W."
TDS Meter
"Buce plant got the meter and the rest of my order to me immediately. Since I live int the middle of nowhere, that’s amazing. The TDS meter needs batteries to run that do not come with it. Additionally, there is no explanation as to how to insert the batteries. Good Luck is you order one."
