SATO SK-6600T, SK-5600TRH nhiệt ẩm kế kèm dây cảm biến 3m (−50.0°C~ 70.0°C)

SATO Keiryoki, Japan 

Model: 

Digital thermometer (with alarm) SK-6600T

Digital thermometer and hygrometer (with alarm) SK-5600TRH

The Sato Keiryoki SK-6600T and SK-5600TRH belong to the same industrial design family but serve fundamentally different environmental monitoring roles: the SK-6600T is exclusively a thermometer, while the SK-5600TRH is a thermohygrometer that tracks both temperature and humidity.

Digital thermometer and hygrometer (with alarm) SK-5600TRH

• Sensor Elements: Uses a semiconductor sensor for internal temperature, a thermistor for external temperature, and a capacitive sensor for humidity. [
• Sampling Rate: Refreshes data approximately every 10 seconds. 
• Alarm Limits: Upper and lower boundaries are configurable across the full scale in increments of 0.1°C and 0.1%rh. 
• Alert System: Emits a buzzer sound—adjustable to High (~75 dB), Low (~55 dB), or OFF—and triggers a flashing red LED when thresholds are breached. 
• Water Resistance: The sensing tip of the external probe is rated to JIS C 60529 IPX5 (waterproof against jets, but cannot be submerged in water).
• Power Supply: Operates via 2 AA alkaline batteries or continuous USB Type-C power input (5 VDC / 0.5 A).
• Physical Profile: Measures 100(W) × 100(H) × 33(D) mm and features a minimalist square profile that blends seamlessly into spaces

• Cold Chain & Food Storage Monitoring: The external probe can be routed into deep freezers or commercial refrigerators (down to −50.0°C) to prevent product spoilage, while the main body monitors the kitchen or warehouse staging environment.
• Industrial Warehousing & Cleanrooms: Essential for tracking strict humidity baselines (5% to 95%rh) to safe-keep sensitive components, raw chemicals, or paper stock from moisture damage.
• Server Rooms & IT Closets: Deployed via continuous USB-C power to protect computing servers around the clock against sudden cooling failures using loud audible alerts.
• Agricultural Greenhouse Management: Ideal for measuring extreme outdoor climate points with the 3m probe, ensuring crops stay within viable humidity parameters.
• Residential Living Space Comfort: Perfect for household spaces where individuals can switch layouts between the desktop fold-out stand or the built-in wall-mount hanger.

 

• Deep Freezers & Cold Chains: Ideal if you only need strict temperature monitoring down to −50.0°C in industrial walk-in freezers, cryo-chambers, or medical cooling boxes. 
• Dual-Zone Fluid/Air Tracking: Best suited for comparing two isolated areas at the same time (e.g., inside vs. outside a server enclosure). 

• Moisture-Sensitive Warehouses: Essential for facilities storing paper goods, electronics, raw chemical powders, or agricultural items where relative humidity (rh%) shifts cause damage. 
• HVAC & Server Rooms: Deployed when static electricity risk (low humidity) or condensation hazards (high humidity) must be guarded against alongside temperature shifts. 
• Laboratory Cleanrooms: For compliance environments requiring concurrent tracking of ambient indoor moisture standards alongside targeted cold storage.
