| The sapphire light guide structure reduces the impact of stray light, while the light window is not easily worn; |
Titanium alloy housing for better corrosion resistance and can be used in seawater environments; |
With self-cleaning brushes to prevent bio-adhesion and longer maintenance intervals; |
Built-in calibration parameters for easy field use and secondary calibration; |
Adopt LED LCD display, intelligent Chinese/English menu operation; |
Output signal: software selects 0-20mA or 4-20mA output; |
High-resistance preamplifier: high input impedance, anti-noise, strong anti-interference ability; |
Multi-parameter display on the same screen: Simultaneously display pH (or ORP) value, temperature value, two current outputs and relay working status; |
Self-set password: Users can set or change their own passwords to avoid misuse by uninvolved personnel. |
