Rod Digital Thermometer Water-Resistant ST 50-300

NIST-traceable precalibration means you get reliable measurements right out of the box, saving you time and money.

|Waterproof/Shockproof Thermometer replaces hazardous mercury units. Stainless-steel probe is resistant to most laboratory chemicals. Wide range covers 99 percent of the lab’s routine temperature measurements: –58 to 572°F and –50 to 300°C. Resolution is 0.1° from –20 to 200°; 1° outside this range. Accuracy is ±1°C between 0 and 100°C. Reading updates every second. At the touch of a button, memory recalls highest and lowest temperature readings over any time period. Reading is updated every second. Solid-state construction eliminates dangers inherent in breakable glass and toxic mercury thermometers. Includes NIST cert.

Rugged, Water-Resistant Temperature Monitoring with the Rod Digital Thermometer ST 50-300

Designed for demanding environments where moisture, splashes, or humidity are present, the Rod Digital Thermometer Water-Resistant ST 50-300 delivers fast, accurate, and reliable temperature measurements from -50°C to +300°C (–58°F to +572°F). Ideal for food safety, industrial maintenance, laboratory use, and HVAC applications, this IP67-rated thermometer combines a durable stainless steel probe with a fully sealed, water-resistant body for worry-free operation in wet or challenging conditions.

Built for Wet, Harsh, and High-Temperature Environments

The ST 50-300 Rod Digital Thermometer features a food-grade stainless steel probe (typically 3–6 mm diameter, customizable length) with rapid response time (<4 seconds) and high thermal stability. Its IP67-rated housing ensures full protection against dust ingress and temporary immersion in water—making it perfect for washdown areas, outdoor use, or steam-rich environments like autoclave validation or cooking lines.

Extended Range: -50°C to +300°C – Covers ultra-low freezer temps to high-heat industrial processes with ±0.5°C accuracy (±1°C at extremes).
IP67 Water & Dust Resistance – Withstands splashes, rain, cleaning sprays, and brief submersion (up to 1m for 30 min).
Stainless Steel Probe (304/316 SS) – Corrosion-resistant and safe for food, pharmaceutical, and chemical contact.
Backlit LCD Display – Clear, easy-to-read results in low-light or steam-filled settings.
Data Hold & Max/Min Function – Capture and review critical temperature peaks during monitoring.
Long Battery Life + Auto-Off – Over 1,500 hours of use; conserves power when idle.

Trusted Where Reliability Meets Safety

From checking refrigerated transport and blast freezers to monitoring oil baths, engine components, or pasteurization systems, the ST 50-300 meets HACCP, ISO, and GMP requirements for temperature verification. Its rugged design eliminates concerns about accidental spills or cleaning—ensuring consistent performance in real-world conditions.

Whether you’re a quality control technician, chef, or plant engineer, this water-resistant digital thermometer gives you confidence in every reading—rain or shine, steam or ice.

Precision you can trust. Protection you can count on.
