This cart-type gas detector detects leakage by drawing in gases on the ground surface.This product features GPS and speed exceedance alarm functions added to the conventional cart-type gas detector (model: XP-707II). Thus, it can record survey results more accurately and further increase the accuracy of leak surveys.

| Model | XP-707IIIai (new product) | XP-707II (conventional product) |
|---|---|---|
| Gas to be detected | City gas (main component: methane) | |
| Detection principle | Hot-wire semiconductor | |
| Detection range | 0 to 30, 0 to 100, 0 to 10,000 ppm (three ranges: S, L, H) | |
| Alarm set value | L/H range: 20 ppm (start of intermittent sound), 100 ppm (start of continuous sound) S range: 0 to 30 ppm (The specific concentration to start the intermittent sound can be set.) |

| Alarm indication | ●LCD indication Remaining battery level, pump operation, data storage (main unit, SD card), GPS signal status, buzzer sound (large, small, off), error (pump error, sensor error, remaining battery level alarm, main unit error), Bluetooth, speed exceedance alarm setting, gas concentration bar graph, Bluetooth earphone, various settings ●LED indication ・Error indication: one red/yellow LED (two-color LED) * Pump error, sensor error, remaining battery level alarm, main unit error: blinking (red) ・Gas alarm: blinking and lit up (red) ・Speed exceedance alarm: blinking (yellow) |
Gas detection The gas concentration is indicated by the indicator lamp.When the gas concentration exceeds the alarm set value, a buzzer sounds (change from intermittent sound to continuous sound). Sensor error The left hand part of the gas concentration indicator lamp lights up.A buzzer sounds (intermittent sound). * The sensor and pump stop automatically. Pump error The right hand part of the gas concentration indicator lamp lights up. A buzzer sounds (intermittent sound). * The sensor and pump stop automatically. |
