Atlas Scientific at Circuitrocks — Lab-Grade Water Quality for Arduino, ESP & Raspberry Pi
Build dependable aquaponics, hydroponics, reef, and lab monitors with Atlas Scientific probes and EZO™ circuits. Measure pH, EC (conductivity/TDS/salinity), DO (dissolved oxygen), ORP, and temperature with I²C/UART interfaces that drop into Arduino, ESP32/ESP8266, and Raspberry Pi projects.
EZO™ circuits • pH/EC/DO/ORP probes • RTD temp • Calibration & isolators
Why choose Atlas Scientific

Featured categories
EZO™ Measurement Circuits
Probes & Accessories
- pH probes (Lab/Industrial)
- EC probes (K=0.1/1.0/10)
- DO & ORP probes • BNC
Calibration & Fluids
- pH 4.00 / 7.00 / 10.00
- EC standards (84 µS, 1.413 mS, 12.88 mS, 50 mS)

FAQ
Are Atlas probes compatible with Arduino/ESP/Raspberry Pi?
Yes. Use EZO™ circuits over I²C or UART. We recommend an isolator to prevent ground loops when probes are submerged.
Which EC probe constant should I pick?
K=0.1 for very low conductivity, K=1.0 for general-purpose (hydroponics), K=10 for high salinity/industrial.
How do I care for a pH probe?
Rinse, never wipe the glass; store in KCl storage solution (not dry, not DI water). Re-calibrate regularly (pH 7 + 4/10).
Do you ship nationwide?
Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
