What is Thermo Scientific DTT used for?
Learn more Thermo Scientific DTT (DL-Dithiothreitol; Clelands reagent) is used to stabilize enzymes and other proteins, which possess free sulfhydryl groups. It has been shown to restore activity lost by oxidation of these groups in vitro. DTT quantitatively reduces disulfide bonds and maintains monothiols in a reduced state ( see Reference 1).
How does a digital thermocouple thermometer work?
A digital thermocouple thermometer needs two measurements to determine temperature. First, it has a sensor to measure the temperature where the thermocouple connects to it – this is known as “cold-junction compensation (CJC). Secondly, it measures the mV signal from the thermocouple.
How accurate are digital thermometers?
The accuracy of the digital thermometer mostly lies in both the analog and the digital worlds.
What is a digital thermistor thermometer?
A digital thermistor thermometer provides an excitation voltage or current to the thermistor. Because the thermistor change in resistance is large compared to the resistance of the leads, a thermistor usually has a 2-wire connection.

An Err message can appear on the thermometer's display if: the sensor is too warm before powering on the thermometer. the temperature reading is incomplete. the thermometer has an internal problem.
Do you add a degree with a temple thermometer?
A temporal thermometer will read at about 0.5 to 1 degree lower than an oral thermometer, so you need to add 0.5 to 1 degree to get what your temperature would read orally. For example, if your forehead temperature read as 98.5°F, you could actually have a low-grade fever of 99.5°F or higher.
Why does my digital thermometer give me different readings?
Differences between measurements can also result from the following factors: The thermometer is not the same temperature as the room you are measuring in (Example: it has been in a much warmer or colder room). The thermometer is inserted into the ear canal at a different depth or angle.
How accurate is a temple thermometer?
A forehead (temporal) scanner is usually 0.3°C (0.5°F) to 0.6°C (1°F) lower than an oral temperature.
Why is my digital thermometer not working?
Replace the battery The flexible tip thermometer has a long-life battery which should last for about 2 to 3 years. If the battery is low, you can replace the battery as follows before using the thermometer: Remove the battery compartment cover. Use an insulated probe to remove the battery (e.g. a toothpick)
What does the L mean on a thermometer?
The “L” means that the thermometer is at its lowest point and ready to take your temperature.
Does low battery affect thermometer?
As long as the thermometer is ready for measurement, it offers the same accuracy. When battery power is too low, the thermometer shows a low battery symbol and does not perform any measurements until the battery is replaced.
Why is my digital thermometer not working?
Replace the battery The flexible tip thermometer has a long-life battery which should last for about 2 to 3 years. If the battery is low, you can replace the battery as follows before using the thermometer: Remove the battery compartment cover. Use an insulated probe to remove the battery (e.g. a toothpick)
How do you fix the LO in a digital thermometer?
The 'Lo' or 'Hi' indications on the display mean that the temperature cannot be measured because the temperature is outside the temperature range. Press the on/off button to switch off the thermometer. Check if it is correctly positioned, press the on/off button again to switch it on, and re-start the measurement.
How do you know if your digital thermometer is broken?
Pour cold water into the glass right up to the brim, then stir it for 15 seconds. Insert your thermometer into the water without touching the sides of the glass. After 30 seconds, your thermometer should read 32° F. If it doesn't, it may need to be replaced or recalibrated.
How do you calibrate a thermometer?

And turn the head so the pointer readsMoreHold the adjusting nut under the head of the thermometer. And turn the head so the pointer reads zero degrees Celsius.
How does a digital RTD thermometer work?
A digital RTD thermometer is, in essence, an ohmmeter. It measures the resistance of the sensor. To do this, it applies either a very small excitation voltage or current to the sensor and measure the voltage across the sensor. A 4-wire connection is often used to minimize measurement errors – 2-wires to carry the excitation, 2-wires to measure the voltage across the sensor. Very precise systems also reverse the polarity of the excitation and average the two readings to remove and inductive, capacitive and thermocouple effects. Some also pulse the excitation to minimize self-heating of the sensor due to the excitation power.
How do thermometers work?
This is a brief overview of how digital thermometers work. 1 A thermocouple has a self-generated mV signal that is proportional to the difference in temperature between its two ends. 2 An RTD is a resistor that changes its resistance near linearly with temperature. 3 A thermistor is a resistor that changes its resistance in a non-linear way with temperature. 4 A solid state sensor requires external power and emits a small linear voltage proportional to temperature.
Why does a thermistor have a 2 wire connection?
Because the thermistor change in resistance is large compared to the resistance of the leads , a thermistor usually has a 2-wire connection. The excitation is converted to a voltage signal by the thermistor and the thermometer then converts the measured voltage to temperature.

What is the temperature of the temple?
During the day it can range from 95.9 to 100.0°F (35.5 to 37.8°C). For some people there can be a difference between their temple and body temperature. We recommend learning your normal temple temperature while healthy so you can detect an elevated one when you are sick.
Can children use a thermometer?
Children should not use the ther- mometer without adult supervision. Do not drop or expose thermometer to electric shock as this may adversely affect its performance. The thermometer is not water proof. Do not immerse in water or liquid of any kind.
Is it important to know your body temperature?
Human body temperature varies from person to person and a person’s body temperature can fluctuate throughout the day. Therefore, it is very important to know your normal body temperature range . Thus we recommend measuring yourself when healthy to establish reference temperatures which will help you feel more confident of the measured temperature when ill.
