KTH2-R series is a high-accuracy, probe-type temperature and humidity transmitter that operates on a DC 7~30V power supply and utilizes an RS485 interface with the ModBus-RTU protocol to achieve a communication distance of up to 2km.
| Product Model | Probe Material | Dimensions | Communication Interface | Protocol | Operating Voltage | Max Distance | Price (USD) | Target Applications |
|---|---|---|---|---|---|---|---|---|
| KTH2-R-M | Sintered Stainless Steel | 56*14 mm | RS485 | ModBus-RTU | DC 7~30V | 2 km | $8.59 | Heavy-Duty & High Strength: Outstanding mechanical strength, high temperature resistance, and effective dust filtering. Ideal for harsh industrial workshops with potential collision risks. |
| KTH2-R-PE | Sintered Polyethylene (PE) | 75.5*16 mm | RS485 | ModBus-RTU | DC 7~30V | 2 km | $5.88 | Dustproof & Anti-Condensation: Excellent breathability coupled with hydrophobic properties to prevent water droplets penetration. Perfect for high-humidity environments, agricultural greenhouses, or outdoor weather stations. |
| KTH2-R-PVC | Polyvinyl Chloride (PVC) | 68*16 mm | RS485 | ModBus-RTU | DC 7~30V | 2 km | $5.88 | Compact & Acid-Alkali Resistant: Lightest weight and most compact length with solid chemical stability. Best suited for indoor server rooms, smart warehousing, or space-constrained monitoring setups. |
