Frequently Asked Questions (FAQ) for Sato Keiryoki PC-5410TRH:

1/ What is the PC-5410TRH thermo-hygrometer?

The PC-5410TRH is a desktop/wall-mount digital thermo-hygrometer from Sato Keiryoki that simultaneously measures ambient temperature and relative humidity. It continuously displays current, maximum, and minimum readings on a large LCD screen, and offers audible and LED alarms when thresholds are exceeded.

2/ What temperature and humidity ranges, resolutions, and display size does it offer?

- Temperature range: 0.0 to 50.0°C

- Humidity range: 20.0 to 95.0%RH

- Resolution: 0.1°C and 0.1% RH

- Display dimensions: 182mm (W) × 92mm (H)

These specs make it ideal for indoor environmental monitoring.

3/ How accurate is the measurement?

- Temperature accuracy: +/-1.0 °C (10 - 40°C), +/-2.0°C (outside that range)

-  Humidity accuracy: +/-5 %RH (20 - 30°C at 40 - 80% RH), +/-8 % RH otherwise

Accuracy varies slightly depending on the measurement band.

4/ What sensing principle does it use?

Temperature is measured by a thermistor-based resistive sensor and humidity is detected via a polymer-resistance element. The onboard electronics convert these signals into digital readings shown on the LCD.

5/ How do I read the current, max, and min values?

- Press the MAX/MIN button to toggle between real-time, highest, and lowest values since the last reset.

- Hold the button for 3 seconds to clear stored max/min data and start a new monitoring session.

6/ How do I set alarm thresholds and adjust the buzzer?

- Enter alarm-setting mode by pressing SET.

- Select temperature or humidity, then choose upper or lower limit.

- Use the arrow keys to adjust in 0.1 increments.

- Exit to save.

The built-in buzzer volume can be turned off or set to low/ high via a thumb wheel on the side.

7/ What is the sampling interval?

The PC-5410TRH updates its display roughly every 30 seconds, ensuring near real-time monitoring of environmental changes without excessive power drain.

8/ What powers the unit and how long do batteries last?

- Power source: Three standard AA batteries

- Typical battery life: Approximately 2 years (assuming daily alarm events)

A low-battery indicator reminds you when it’s time to replace them.

9/ How can I install or mount the device?

- Desktop: Flip out the integrated stand.

- Wall-mount: Hang via the keyhole slot on the rear panel.

This dual-mount design offers flexible placement in labs, warehouses, offices, or greenhouses.

10/ Does it require calibration or maintenance?

- Recommended calibration: Every 1 - 2 years to maintain accuracy.

- Care: Keep sensor area free of dust, avoid direct sunlight or corrosive vapors.

11/ Can it be used outdoors?

By default, the PC-5410TRH isn’t weatherproof. To use it outdoors, place it inside a ventilated, waterproof enclosure and shield it from direct rain, dust, and extreme temperatures.

12/ Does it support data output or computer connectivity?

The standard PC-5410TRH has no serial or USB port. If you require data logging, consider pairing it with an external data logger or choosing a model with built-in communication interfaces.

13/ Are there optional accessories or certificates available?

- Calibration certificate (ISO-traceable)

- Spare polymer humidity sensor modules

- Protective silicone sensor caps

- Custom mounting brackets
