Bi
- Metallic Dial Thermometers
|
Haridas Instruments & Equipments Co. manufactures Bi-metallic Dial Thermometers under the
brand name of EaSee.
EaSee Stainless Steel Dial Thermometers are used extensively by Industries,
Laboratories, Processors, Universities and Government agencies all over. Easy to read dials,
rugged construction, leak proof welds and guaranteed accuracy assures the discriminating buyer
of the finest thermometer which is also easily withing reach of even the most modest budget.
|
 |
| Accurately calibrated
The most precise calibrating methods are used in the fabrication,
calibrating and testing of each sensing helix coil before it goes into an EaSee thermometer.
Experienced engineers and craftsmen ensure precise production of each unit in every phase of manufacturing.
|
Easy to read
Clear, crisp, raised marks and numbers on the dial
provide exceptional readability. The double anodised aluminium dials with stain matte finish
back-ground and black raised marks and numbers assure minimum parallax.
|
Rugged and reliable
The all metal construction, except for the optically
clear glass of the thermometers and their specially welded fabrication make them virtually
unbreakable. The type 304 stainless steel stems offer exceptional protection against highly
corrosive materials. Stainless steel stem, plugs and mounting nuts are actually fused together
to form a perfect moisture-proof bond. Each EaSee thermometer is meticulously manufactured
step by step to produce a most efficient precision thermometer.
|
|
Available in a wide variety of dial sizes, stem lengths, mounting connections and temperature
ranges, EaSee Thermometers offer the user much flexibility in selecting just the right
configuration to meet virtually every temperature requirement. These accurate thermometers have
been manufactured to the very highest standards of excellence by expert craftsmen using the finest
materials available. |

Thermocouples & RTD's
|
 |
Thermocouples
Thermocouples are extremely robust and offer the highest
level of tolerance to shock and vibration. The various types cover a temperature
range from -270° C to +1700° C. They can be produced in extremely small diameters
where speed of response is a critical factor. |

Sheath Materials
A wide range of standard sheath materials are available,
including Stainless Steel Types 310, 316 and 321, Inconel 600, Re-crystallised Alumina,
Ceramic, etc. |

Resistance Temperature Detectors
Platinum Resistance Sensors offer the highest standard of
accuracy and stability of any temperature sensor. They exhibit good linear
response, covering a range from -200° C to +650° C. They require no special cables
or cold junction reference. |
Conductors
Standard RTD's are 100 ohms at 0° C, in two, three or four wire configuration.
Single and Duplex type RTD's are available
as standard. |
Sheath Materials
A wide range of standard sheath materials are available,
including Stainless Steel Types 316 and 321 and Inconel 600. |
