12 best tester with hfe measurements
A tester with HFE measurements refers to a type of multi-tester or electrical testing instrument that includes a function for measuring HFE (heterojunction bipolar transistor forward current gain) or transistor gain. Here's some information about this type of tester:
Multi Tester: A multi tester, also known as a multimeter, is a versatile electrical testing tool used by electricians, technicians, and DIY enthusiasts to measure various electrical parameters.It typically includes functions for measuring voltage, current, resistance, and sometimes additional features like capacitance, frequency, and temperature.
HFE Measurement: HFE, or transistor gain, is a critical parameter in the testing and characterization of bipolar junction transistors (BJTs). It quantifies the amplification capability of the transistor. HFE measurements are particularly important in electronic circuit design and troubleshooting to ensure that transistors are functioning within their specified parameters.
A tester with HFE measurements, therefore, is a multi tester that includes a function specifically for measuring the HFE of bipolar junction transistors. This feature allows users to test and verify the gain characteristics of transistors, ensuring they are suitable for their intended applications.
These testers often come with a transistor testing mode, which enables users to identify the pin configuration of the transistor and measure its HFE. This information is crucial for determining if a transistor is functioning correctly and if it meets the requirements of a particular electronic circuit.
In the context of "Tools Home Improvement," having a tester with HFE measurements can be valuable for individuals who work with electronics and need to troubleshoot or repair circuits that use transistors. It helps ensure the proper functioning of electronic components and contributes to the overall reliability of electrical systems and devices.

User questions & answers
Question: | do you have rechargeable batteries? works with 110v? and does it measure blood pressure too |
Answer: | Three red lights indicate full battery. |
Question: | My elderly mom who has copd and renaud's syndrome has a hard time getting a reading. is this pulse oximeter sensitive enough |
Answer: | Depends how you mean pulse rate. Accurate pulse rate is maybe 1 in 10 inaccurate much better percentage. Please do not buy this if you require a accurate reading for health reasons. |
Question: | who do i contact if this does not work |
Answer: | Hi! My name is Sara and I am with Beyond Med Shop. Usually, it takes about 10 seconds after turning on the oximeter to get a reading. Please note though that when your blood perfusion level is low or when your hands are cold, the device may need more time to optimize and register an accurate reading. In this instance, we suggest that you warm your hands and fingers before taking the measurements. You can do this simply by rubbing your hands together. Remember your pulse oximeter is measuring your SpO2 and PR based on your blood flow. If the blood flow in your finger drops below a certain level, the pulse oximeter will not be able to function. I hope this helps. Please email us at cs@beyond medshop.com if you require additional information. |
Question: | where is it manufactured |
Answer: | Yes I have and the heart rate is very close. I have several of these and COPD and this ones heart rate at least the one that I have is very good. On the cell phone app which is called Oximeter the oxygen sensor is way off like 5 points high which is critical and I was told that the cell phone oximeter was more designed for sports than for actual health problems! as an example a five point spread could cause major organ damage do to low oxygen! |

500DL Pro Series Pulse Oximeter
The 500DL Pro Series Fingertip Pulse Oximeter was born primarily due to customer’s frustration with the CMS 50DL. The CMS 50DL was slow, sensitive to movement, inaccurate under indoor lighting and was able to read SpO2 only up to 99%. Now you can accurately and reliably determine your SpO2 (Blood Oxygen Saturation Levels), Pulse Rate and Pulse Strength. Designed for sports enthusiasts, aviators, trainers, bikers, mountain climbers or anyone who wants to obtain their SpO2 on the go.
Accurate and Reliable
Our Pro Series pulse oximeter accurately determines your SpO2 (blood oxygen saturation levels) within +/- 2% deviation.
Hypoallergenic
Constructed with a high quality medical grade silicone finger chamber that is hypoallergenic and latex free.
SpO2 Levels Reach 100%
Blood Oxygen Saturation Level values now reach up to 100% and SpO2 and Pulse Rate now faces the user.
Easy Battery Removal
Our quick snap-off battery cover allows you to place and remove batteries completely hassle-free.
Frequently Asked Questions
Q: How do I know the battery is low?
A: Please note that the flashing battery icon that appears each time you turn on the device indicates that the device is checking the power supply. It disappears after 2-3 blinks. If the battery icon remains on the LED display, then it is an indication of low battery level.
Frequently Asked Questions
Q: How do I turn off the pulse oximeter?
A: The 500DL pulse oximeter turns off automatically in 16 seconds after you remove your finger.
Frequently Asked Questions
Q: Can the 500DL Pulse Oximeter be used on children?
A: Yes. However, we highly recommend using our children pulse oximeter instead which is specifically made for children. The finger chamber of the 500DL Pulse Oximeter may be too big for children with small fingers. This can affect the accuracy of the reading.
