HYP Series
OMEGA® Hypodermic Needle 
Temperature Probes are 
designed for industrial, laboratory, 
manufacturing and chemical 
research applications. Five probe 
types are available, with diameters 
from 0.2 to 1.65 mm (0.008 to 
0.065"). The HYP0, HYP1 and 
HYP2 have type T (CopperConstantan) thermocouple elements, 
while the HYP3 is available in J, K, T 
or E calibration, and the HYP4 has a  
100 Ω Platinum RTD (a = 0.00385).
Thermocouple Probe Model HYP0
The HYP0 mini-hypodermic probe with a needle 
diameter of only 0.2 mm (0.008") is the least likely 
to disturb the surrounding insertion area. Binocular 
microscope micro-manufacturing techniques result 
in an extremely small Type T (copper-constantan) 
thermocouple being implanted in a 33 gauge, 
25 mm (1") long stainless steel hypodermic 
needle. The HYP0 has the fastest response of 
the hypodermic probes, and has a continuous 
temperature rating of 200°C (400°F). It has 1.5 m 
(5') long PFA-coated, 36 AWG leads with an  
SMP-type miniature connector.
The HYP0 is a mini-hypodermic 
probe, with 0.2 mm (0.008") 
diameter. The HYP1 has an OD of 
0.3 mm (0.012"), and has an added 
feature of being steam autoclavable 
to temperatures up to 160°C (325°F). 
The HYP3 and HYP4 are industrial 
probes, with thermocouple and RTD 
elements respectively.

Thermocouple Probe Model HYP1
OMEGA® Research, autoclavable probe is designed to 
give instant readings in plants, other semi-solids and 
liquids. A 30 gage x 15 mm needle provides this very 
fast response. The measurable temperature range is 
cryogenic to 200°C (400°F). This is a Type T (CopperConstantan) grounded-junction probe with PFA insulated 
extension wire and a subminiature male connector 
termination. The entire assembly is steam autoclavable 
to a temperature of 160°C (325°F). All probes have 
1.5 m (5') leads.
