• • Loud buzzer: Features a switchable dual volume control reaching up to 80dB (loud).
  • Visual LED flash: Can flash brightly to catch your eye if you cannot hear the buzzer.
  • Three notification modes: Configure it to alert via "Sound + Light", "Sound Only", or "Light Only" (ideal for quiet laboratory settings where noise is forbidden).

• • 5 Distinct Sound Patterns: You can assign a different tone pattern (e.g., pi-pi, pi-pi-pi, etc.) to individual devices to easily distinguish whose timer is going off.

• Repeat Function: Automatically reverts back to your previously set time once the countdown finishes. Perfect for repetitive tasks like baking, chemical mixing, batch cooling, or strict manufacturing process steps.
• Pre-Alarm Notification: Configurable warning flashes/beeps at 5 minutes, 1 minute, or 30 seconds before the time actually runs out.
• Dual Mounting: Built-in heavy magnets for metallic racks or a standard neck strap hook for mobile portability.

• 3 Notification Modes: Choose between "Buzzer + Light", "Buzzer Only", or "Light Only" for sensitive or ultra-quiet environments. 
• 3 Alarm Durations: Configure the alarm to sound for 30 seconds, 2 seconds, or Continuous (keeps going until you manually press a button). 
• 5 Sound Tones: Program 5 distinct buzzer beep patterns to avoid confusion when using multiple timers in the same facility. 
• Pre-Alarm Warning: Flashes/beeps ahead of schedule; selectable for 5 minutes, 1 minute, 30 seconds, or off. 
• Automatic Repeat Display: Instantly returns to the previously configured countdown time when the alarm cycle ends (excellent for routine tasks). 
• Integrated 12-Hour Clock: Acts as a standard digital clock when the timer system is idle. 
• Key Lock Security: Features a hardware locking function to completely avoid accidental button presses while stored or carried. 
• Versatile Mounting: Dual internal heavy-duty magnets for metallic attachment or a dedicated top slot for the neck lanyard.

The SATO Dekatimer PRO TM-250 Series is engineered for high-durability, sanitation, and clear notification. Because it is completely waterproof (IPX7) and features both high-volume buzzers and flashing light alerts, it is widely applied across several demanding professional industries.

• • HACCP & Sanitation Compliance: Because the device can be completely submerged and washed under running water, it prevents cross-contamination. Workers can clean food grease, flour, or raw juices right off the buttons.
  • Wet-Hand Operation: Chefs, bakers, and line cooks can manipulate the keys with soaking wet hands or heavy rubber gloves without shorting out the device.
  • Deep Frying & Baking Lines: Tracking precise cooking intervals for high-volume batches.
  • Sterilization & Cooling Cycles: Timing the blanching of vegetables or monitoring food cooling windows to ensure health code safety.

• • Machinery & Noisy Areas: The loud 80dB alarm cuts through the hum of factory equipment.
  • Visual Alerting (Light-Only Mode): For workers wearing heavy hearing protection (ear muffs/plugs), the timer can be set to flash its bright LED light to signal a process shift.
  • Process Line Batching: Timing chemical dips, plastic curing, adhesive drying times, or metal heat treatments.
  • The "Multi-Worker" Solution: When 4 or 5 workers operate side-by-side, each timer can be set to one of the 5 distinct beep patterns. Operators immediately know whose machine is ready without looking up.

• • Cleanrooms & Quiet Zones: By switching the unit to "Light Only" mode, lab technicians can accurately track chemical reactions, culture growth, or centrifuge cycles without disturbing sensitive environments or violating noise restrictions.
  • Chemical & Reagent Mixing: The precise 1-second adjustment interval allows researchers to time high-stakes testing down to the exact second.
  • Sanitation-Heavy Clinics: Easy disinfection via alcohol wipes or washing, making it safe for medical prep areas.

• Routine Equipment Maintenance: Mechanics and logistics personnel use it to track equipment warm-up times or battery charging cycles.
• Mobile Field Inspections: Thanks to the included neck strap and key-lock function, inspectors can wear the timer around their neck in the field without worrying that accidental body bumps will change or cancel their countdown settings.
