The Graham Field (Grafco) thermometer series provides accurate temperature monitoring for both clinical environments and patient care. The 1534 Room Thermometer is a classic wall-mounted analog gauge designed for monitoring ambient air temperature in patient rooms, clinics, or laboratories. The 1537 Flat Bath Thermometer is a specialized floatable device used to ensure bath water is at a safe and comfortable temperature for patients, particularly those with reduced thermal sensitivity. Both instruments feature clear, easy-to-read scales and durable construction suited for medical facilities.
