ERKA Precise Dual-Head Stethoscope

The ERKA Precise is a high end stethoscope featuring a dual-head brass chestpiece that can be used for auscultation of higher and lower frequencies in all medical fields. The bell features a non-chill rim and is used for auscultation of lower frequencies, while the special patented design of the dual-frequency diaphragm allows for auscultation of higher and lower frequencies. The separately-integrated spring and the parallel-running channels in the tubing transmit sound without loss and without adding extra grinding sounds from the chestpiece to the user's ear.

 

The ERKA Dual-Frequency Diaphragm

The floating membrane prevents sounds from being transmitted if it is deformed. The membrane is designed so as to withstand day to day use in the practice or clinic, and nevertheless ensures outstanding sound transmission. On the outside–the side that touches the skin–the stethoscope features a strong plastic diaphragm that protects the internal, highly sensitive and extra thin copper-beryllium diaphragm. The space between the two membranes provides extra resonance space and acts as a pre-amplifier. The ERKA dual-frequency diaphragm guarantees perfect auscultation results and a confident diagnosis.

BEST mug warmer
Color: Black
This is the best of the many mug warmers available online. It has 3 temperatures. I use the highest - 167 degrees. I like my coffee HOT. With this warmer I don’t have to return to the microwave as often to reheat my coffee. It is very easy to use- takes large mugs as well as regular sized cups. I have looked everywhere for a “flat bottomed” mug . All the mugs I have found have a rim on the bottom which prevents complete contact with the warmer. However the warmer works with the “bottom rimed “ mugs. I use my warmer for the end table by my recliner. I am considering purchasing a second warmer for my desktop. I definitely recommend this as the BEST mug warmer. I have been using it many hours daily for over a month as I am retired. It works fine. I did just purchase a second one. It came the day after I ordered it. Now I can enjoy a hot beverage by my recliner or on my desktop. I purchased a silicone cover/lid for my mug. This really keeps my beverage hot. However when you remove the lid the condensation on the underside of the lid drips. I keep a paper towel/napkin close by to catch the condensation.

Warming Up to My New Mug Warmer
Color: Black
I keep mine next to my computer monitor so I always have that quick caffeine jolt nearby. The three temperature settings are convenient and the LED readouts ensure your brew is as hot as you want it to be. Not sure about reviews saying this warmer makes drinks lukewarm because it doesn't. In fact, it can be used to reheat drinks in just a few minutes. I also like that it's a 120v plug-in and it's not the weak, slow, and temperamental USB powered one. One tip: The on-off switch is on the underside of the warmer. It must be depressed for it to power on. If the red LED doesn't indicate the temperature, then the warmer is not on (or the button is broken). You don't have to turn the unit over either to press the power button, just press down on your mug until the temperature LED turns on. The other hint is that this warmer can get very hot very quickly. While the edges stay cool to the touch, never touch the outlined hotplate area or you might get burned. Wait for it too cool down or use a pair of oven mitts---it's that hot.

Almost started a fire
Color: Black, Color: Black
This item malfunctioned, a stack of papers about five pages was accidentally placed on top of it, and nearly started a fire. there should not be any heat from this unless there’s something having enough weight engage the heat plate. The paperwork was accidentally set on top of the hot plate, but definitely not heavy enough to engage, and the heat plate is no longer working unless I push down with my hand, a coffee cup is not heavy enough to engage it now so something has malfunctioned . I purchased this last spring and I am no longer eligible for a replacement or refund and just about burned down my office

Keeps beverages warm NOT hot
Color: Black
Doesn’t keep beverages hot, just warm and I love my tea and coffee hot. So I was very disappointed about that but decided to keep it anyway

It works great
Color: Black
It has three heat settings. I like my coffee very hot and its perfect for that. It blinks when it’s turned off and still hot. It’s also durable. If it falls of my coffee table it won’t be damaged. Also not expensive.
