Ozone and VOC detector with display S-O3 UZ/LZ/GZ

Manufacturer: Nesa
Category: Gases - Particles, Meteorology – Climatology, SENSORS, Gas Sensors

The NESA S-O3 UZ/LZ/GZ is an ozone and VOC detector with a display, designed for measuring and monitoring gases and programmed with specific software. It can be used as a simple device (on/off switch) or as a monitoring device (detecting a specific gas concentration over a user-defined period).

Ozone measurement ranges: S-O3 UZ 0–0.15 ppm, S-O3 LZ 0–0.5 ppm, and S-O3 GZ 0–10 ppm; VOC measurement ranges: S-O3 VOC-VM 0–25 ppm and S-O3 VOC-VP 0–500 ppm. Features a 3.5-digit LCD display, relay output, and 0–5V DC or RS485/Modbus output. For outdoor measurement, the S-O3 (0–5 ppm) output is available with a 4–20mA/Modbus output.

Technical Frequently Asked Questions

What does S-O3 UZ/LZ/GZ measure?

The concentration of ozone O3 (UZ, LZ and GZ) and of VOC (VOC-VM and VOC-VP).

What measurement ranges does it have?

Ozone: S-O3 UZ 0÷0.15 ppm, S-O3 LZ 0÷0.5 ppm and S-O3 GZ 0÷10 ppm. VOC: S-O3 VOC-VM 0÷25 ppm and S-O3 VOC-VP 0÷500 ppm.

What exits does it have?

Analog 0÷5V DC (8 bits), digital RS232 and RS485, and 24V relay; 5A (max.).

What kind of diet does it need?

12 V DC, 800mA.

And for outdoor measurements?

For outdoor measurement with 4÷20mA / ModBus output, there is the S-O3 (0÷5 ppm).

How do I order it?

Sensor (S-O3), output (A 0÷5Vdc or C RS485 / ModBus) and accessories: CS05 or CS10 sensor-datalogger cable and SSU sensor support l=750mm. Example: S-O3 A 10 SSU.
